German Aleph-X PCB orders - Click HERE for Original Thread
cocolino
I want to contribute to simplify the distribution for the Aleph-X PCB`s and so hopefully to make this job for Chad a little easier.

As I`m already ordering PCB`s for several German DIY-Audio members anyway, I offer to function as the distributor for other German members too.

So anybody who wants to have the boards shipped to me first please post here in this thread.

I can make the total payment via Paypal. We share all the expenses as shipping and eventually tax/customs (which with some luck I hope we can avoid) and some minor losses due to the currency exchange, prorated on the individual ordered amounts.

here the info I gathered from the Wiki for amounts of boards orderd from German members (hope I did not overlook somebody):

cocolino, Germany, qty:20
HBarske, Germany, qty: 6
ChrisBerg?, Germany, qty: 2
Blitz, Germany, qty: 4
Orgonom, Germany, Qty: 6
Axelcs, germany, qty: 4

total amount of boards: 42
HBarske
Thank you Christoph,
you have been a little quicker than me with opening this thread :D.
I would be very glad if you would care for the distribution in Germany as I don't have a PayPal account. As soon as we have an idea of board's costs I would be happy to transfer some money to you.
HBarske
Just found on the Wiki:

arad, Germany, qty: 8

Cocolino, thanks for taking the initiative and offering your help. I have asked for 8 boards on the WIKI page and sure would appreciate if I could get them via you.

Thanks and keep me posted when and where to send some money

Gruss,
Andreas

Hi there,

this is a great help to take over the orders in germany.
I need 8-12 boards depending on who else wants some from my friends and how much they will cost. when do you think we will have the boards and how much will it cost?
Payment will be a piece of cake. I can transfer the money to your bank account.

Thanks in advance
promitheus
cocolino hi,

I just added myself on the wiki for 10 pieces.
You can get the boards for me through the group order to Germany.
Tell me how much it will cost and how I can pay.
You can put me on the list above.

greetings Ilias

Erstmal Servus (Hallo auf hochdeutsch;) ) an alle,:)

When I get the total including the shipping costs I hope it`s time enough to collect the money in order to send the amount in due time.

Therefore I ask all of You folks PLEASE to send the money as soon as possible once I emailed You what´s Your individual total.

Wire transfer/ Banküberweisung to me is just fine.

The cheapest (UNINSURED) shipping from me to You up to a couple of boards, is Maxibrief - Euro 2,20. If somebody wants to have his boards shipped INSURED (Postpaket Euro 6,90) please let me know!



Regarding the tax/customs issue:
I´m pretty sure we could avoid tax (16% VAT) and customs (only a couple %) when the shipping would be uninsured and marked as "samples", "gift" or something similar BUT I´d honestly feel more comfortable if we have it shipped insured (and then we`ll have to pay around 20% tax/customs almost for sure).

Not that I expect it gets lost or something - I got lots of stuff from US (via USPS) and also Canada in the past and until now everything always worked fine.
It`s only just for the case and as I expect the number of boards
to be something around 60 to 70 finally (or maybe even more), although the price per board will be quite low, in total we`re talking about considerable amount of money here.

As I think the VAT/customs costs will not sum up to more than approximately an additional 1$/per board I believe this should be still reasonable for everybody!?


Now, for being already prepared when I get the total, I ask everybody to send me an email (use the form below - my email here is enabled) in advance, containing the following information:

1.) name (Your real name + Your DIY-Audio nickname)
2.) full adress
3.)confirmation of the number of boards You want to have
4.)How You want to have shipped Your boards from me to You: UNINSURED or INSURED


and here the updated list:

cocolino, Germany, qty:20
HBarske, Germany, qty: 6
ChrisBerg?, Germany, qty: 2
Blitz, Germany, qty: 4
Orgonom, Germany, Qty: 6
Axelcs, germany, qty: 4
arad, Germany, qty: 8
promitheus, Germany qty: 10

total amount of boards: 60



Ihr hört (spätestens) von mir wenn`s soweit ist.
Cradle22
Hi!

Count me in for four boards (right now I am last one on the wiki page)!

Werde überweisen, wenn Betrag feststeht!

Time to go for Aleph, at last (even if it will take between one and two years, because of costs...).


Thanks,

Hi Christoph,

Don't forget the PayPal charges. You'll have to give Chad 4% and you'll also need to receive another 3 or 4% from each one that pays you with PayPal. It's not much to each individual, but it adds up to a lot for the group.
Orgonom
Hallo Christoph,
wäre es noch möglich, statt 6 Platinen 10 zu gekommen? Sobald alles klar ist sende die mail
und ich überweise an Deine Bank.
Vielen Dank und bis bald.

Hallo wieder,

ich bin zurück.
I will make my order 20 pieces. 2 best friends of mine who were waiting for something like this want to make some amps too.

I will update my order in the wiki and send you an email to cocolino with my info.
cocolino
BTW:
I assume (??) that everybody agree on having the PCB`s shipped insured so I surcharge 20% tax/customs (16%VAT + rest estimated customs) on the amount of costs of the PCB`s (not the shipping).
In case I get them (unexpectedly) free of tax though (sometimes it happens that something "slip through" customs) of couse I refund You the according amount later.

Hello Rodd,

thanks very much for mention this - I almost forgot that!
Yes the Paypal charges are about 4% in total for receiving funds from abroads.
I`ll make the payment by funds from my account (have to upload first - this may take up to 3-4 days until money is credited in my PP-account) not from credit card - I only mention it as I recall that this might have something to do with the fee PP charge in the end but Chad sure knows this better than me.
Regarding the payments to me I think everybody will pay by wire transfer as this is the most common and cheapest way here so that`s not an issue.

Hallo Andreas und auch an alle Anderen diesbezüglich,

for me it`s not a problem when You change or update Your amount of order until the time line when Chad announce the order for closed.
I only ask that everybody send me an email which contains the information mentioned in my previous post when You know how much You`ll order finally (when somebody has sent me an email already and still want to change something, of course this is possible - UNLESS the sale has been declared as closed).

now here the updated list from people who have already indicated that they want to join the German group order through me (by now I`ll leave out the other`s from the Wiki who have not yet stated something here at this thread or from those I haven`t heard until now) :

cocolino, Germany, qty:22
HBarske, Germany, qty: 6
Orgonom, Germany, Qty: 10
Axelcs, germany, qty: 4
arad, Germany, qty: 8
promitheus, Germany qty: 20
Cradle22, Germany, qty: 4

makes for 74 so far
promitheus
what is the current price of the boards without the extra costs of shipping? 4 - 5 $ or more?
cocolino
for all people who wants to join this German group order please sign up with Your order not only at the Wiki page but in this thread here also!




And:
I got also a request from Denmark (Hi Martin :wave2: ) maybe to join in here as well (mostly for the reason saving Chad some of the effort to ship to many "single individuals" what I regard as a nice gesture and what I can only endorse) .
I don`t mind to handle some other orders from European countries as well but please be aware that international shipping costs would apply two times which very probably makes things more expensive than shipping to You directly.
Furthermore this wouldn`t make much sense for members from non EU countries as the customs/tax thing applies twice too!

Anyway, everybody who thinks though that it`s more reasonable to join here is welcome.

Ilias,
I don`t know what`s the current price for a board. I recall to have seen an estimation in the main PCB-sales thread recently - yes something slightly over $5 I believe.

By all means here my email-adress:
520075459301-0001@t-online.de


here the actual list for the German group order:

ChrisBerg, qty: 2

total at the moment: 96


Again please don`t forget to send me confirmation email with Your shipping info (it saves me the additonal work to ask everybody for it).
It need not necessarily to be now - just in due time before the sale is going to be closed.
cocolino
Only that everybody is aware of and to avoid surprises here how the final costs of a board will be calculated once I have received the total from Chad:


total costs of all PCB`s
+ international shipping/insurance to Germany
-------------------------------------------
= xxxx $
+ x% Paypal fee (probably 4%)
-------------------------------------------
= xxxx $
+ money conversion from Euro to US$ (today 1Euro =1,18 $ but this may vary a bit from day to day)
-------------------------------------------------------------------------
= xxxx Euro
+ 20% tax/customs(**) - (16% VAT + estimated 4% custom fee) from the costs of PCB`s (see first line of calculation)
-------------------------------------------------------------------------
=xxxx Euro
/divided by total number of boards
= x Euro/ per board

so the individual total which I`ll email to everybody is the amount from the last line of the calculation above, multiplied with the ordered number of boards + the cost for Your choice of shipping (see my second post above ) from me to You (nur tatsächlich anfallendes Porto per Deutsche Post).

(**) in case I get them free of tax/customs (what I don`t expect when we have the boards shipped insured) I refund the corresponding amount later.

Hi Cocolino

Thanks for mentioning me(Martin from Denmark).

Sofare there still nobody in the group order buy of Aleph-X pcb's from Denmark, but I will wait a little longer and see if somebody from Denmark join in on the buy.

If nobody from Denmark joins I will take you up on the offer and join the "German group" to make it easier for Chad. I will return with the final call and if I join I will mail you information. Paypal was an option to pay you was it not?

Best Regards
Martin

Here are the latest news about the PCB order:
http://www.diyvideo.com/forums/show...4069#post284069

Chad said he must receive the payment until January 13.



As I`m out of the country from January 7 for 2 weeks and because I still have to collect the money and send it to my Paypal account (which takes about 3-4 days only until it`s credited there), it`s already almost time to close this German group order!!

Moreover due to the many coming holidays it can be expected that the bank transfers to my account may work slower than usually.


:att'n: So everybody who still wants PCB`s or who wants to change and update his order please sign up on the WIKI page (or change Your existing entry) AND send me a confirmation email with the following information (or for those who have send me an email already just post here):

name
DIY-Audio nickname
quantity of boards
shipping adress
prefered shipping method from me to You: insured or not :att'n:

until Friday Dezember 19 (22°° European Time) :smash:




I got confirmation emails from all people listed in my previous post exept from:
fschlenk
Orgonom


On Saturday I`ll send an email to Chad (hifizen) asking for the shipping costs. I´ll send him the list of people and quantity of ordered boards from this group order.

When I got this information I`ll calculate Your individual totals and send everybody an email with my bank information until end of the weekend.

BTW: in order to avoid a big mess - BY ALL MEANS please include the intended use (Verwendungszweck) for Your payment to me which I`ll name You in my email !!


After that I ask everybody to transfer me the named amount PLEASE AS SOON AS POSSIBLE!

Thank You!:)

The emails through the DIY-Audio.com server seem to have some problems!! Yesterday and today I got about 100 emails (delayed)from old threads I have subscribed to and also from DIY-Audio.com members contacting me about this group buy.

Therefore again, please use this email adress to contact me:

I still get emails asking if it is enough to send me an email so as to order. No - You have to edit the WIKI and to enter Your name, country and quantity of boards (and to change the total of boards at the end of the list) on the WIKI page ALSO.
The WIKI is here:
http://www.diyaudio.com/wiki/index....+Jan+2004+Order

Only DIY-Audio.com members have to and can edit the WIKI.


This only as I have a few requests from non DIY-Audio.com members too (or from people not speaking english respectively ). For those I update MY ordered amount in the WIKI.

When he replied to me with the shipping info, everybody from the list above get an email from me with payment instructions.

Please read the instructions closely and make Your payment AS SOON AS possible!

If there are any news noteworthy, I`ll post them here.

Thanks to all for the very good cooperation so far - I hope it keeps going that way;)

I have sent an email to everybody(*) with detailed calculation of board costs after shipping/tax/duty/fees etc., my bank information and payment instructions and various other information.

(*) from the final list which can be seen in my previous post including those people for I have ordered in my name.

A note about the shipping method:
as the USPS GEM (Global Express Mail) was only slightly more expensive than the ordinary Airmail parcel service I opted for this after Chad suggested it to me.
It`s not only faster but it has the big advantage of being trackable.
cocolino
Accidentally I just noticed that in the last line of the calculation (total amount divided through 198 boards) for a single board, the amount is not correctly stated (it should be replaced with the amount from line n.) ) - the result is correct though :angel:
I must have been a little tired after all that numbers :dead:
Sorry!

Unfortunately, I have missed the group order. Should anybody from the German PCB group order want to get rid of two boards, I would be glad to buy them.:bawling:

Hallo Ilias,

first, a Happy New Year to everybody!

I have received payments from almost everybody.
From those I haven`t yet received the payment, I`ve the confirmation that they`ve made the transfer.

Very smooth transaction so far - great cooperation guys - thank You!!:cool:


Anyway, I´ve transfered the total amount to my PayPal account a couple of days ago.
I expect to arrive the money tomorrow (at least I hope so). Immediately after it is credited there I`ll send it off to Chad.

After the payment is off, for the time being my part is finished until the boards arrived here.

For news about when the boards have been shipped from US watch for Chad`s announcement at the "New Aleph-X PCB group order..." thread.

I`ll let You know again when I`ve sent PP payment to Chad actually.
Krabbenkoenig
Hello!
Well, I just noticed this thread and since I've been looking for a decent, nice DIY amp, although I'm from Austria I'd ask if it is still possible to take part in this order.
I would need 2 PCBs.

cocolino
PayPal money transfer to Chad for the German group order is completed:checked:

I`m glad the money is out of my responsibility now (those internet "big" money transactions always make me a bit nervous -an electron or two fail to do what they should and there is big trouble):D


At the moment there are only 2 payments missing but I`ve got respond that the transfers are made.



As I said earlier I`m leaving to Spain :p in about 24 hours and I`m back at January 21. .

You`ll hear from me again (at the latest) when I`ve received the boards.

Prepare Your soldering irons and have a good time meanwhile!



P.S.: Krabbenkoenig already got email from me

HEY,

Can´t wait to get the boards.

hi.

just wanted to add we have lots of heatsinks , fets (irfp 240 and 9240) and some transformers suitable for aleph-x.

let me hear if you are interested , we think a group buy is better here.

Hi folks:),


I`m back from holidays (20°C difference between Spain and here... brrrrrr).

Almost daily I get requests if I know something new about the Aleph-X PCB`s.
No, I don`t but there is no reason to worry about.

As it looks like, at the moment Chad (Hifizen) is still collecting money and organizing/ preparing things to get the boards shipped out.
He has confirmed that he received our payment.

Again, please look at this thread for any new announcements from Chad. Very likely he will post when the first boards are on their way.
http://www.diyaudio.com/forums/show...9770#post309770

I expect the boards to arrive here approximately in the middle of February but this may depend much from our German customs also.

I understand that many of You are very curious to get the boards but don`t worry guys and please stay patient (bear in mind that Chad overtook a really huge work with this group buy for us and that this things will take its time).
In any way I`ll let You know immediately when there is something relevant You should know.

PS.: meanwhile I`ve received ALL payments - Thank You!:cool:

Today got the notification from Chad that the PCB`s are shipped out the day before yesterday.

I`ll let You know when they arrived at my home finally.
Due to the customs thing this might last a few days more but I expect them to arrive in about a week at the latest (assumed that things concerning customs transaction go hassle-free).

Chad (hifizen) has another 200 leftover PCB`s for sale soon. You might contact him directly.

I will not have some leftovers but I have some questions:

can anyone please tell me where I can have the schematic, mounting plan and maybe a part list for THIS pcb?

Do I need selected/matched transistors?

Sorry, I do not really want to use the search button, the original thread is far too long to read through...

How about a parts group order? ;)

Cheers
Christian.
HBarske

Great idea, as we need matched FETs. Buying a reasonable lot (Reichelt?) and getting the selection process "centralized" could help a lot.

@Julius20: I think I might be able to help you.
Hardi
quote:

Hello,

buiyng parts for high quality projects from "Reichelt" is always a risk. It´s not impossible to get different manufactors when buying a larger amount. I would inquire before.

Hardi
krishu
Since we need not only IRF9610 and IRF610 we will have to order from Farnell or RS anyway. Some parts they sell only in hundreds, which would be no problem when group-buying. But who would want to do the work?

I suggest we group-buy only transistors & ICs, maybe some special caps as well as the diodes. But nobody could sort all those resistors.

I guess some of You are already nervous :D - I have the cure for You - take a look here - I have attached a picture :bigeyes: :

http://www.diyvideo.com/forums/show...8774#post328774


I try to find time to pack and send out everything before this weekend!

I suggest we group-buy only transistors & ICs, maybe some special caps as well as the diodes. But nobody could sort all those resistors.
regarding parts - I have a bunch of nice very high-power (real!) dual Schottky diodes for sale - great for X-Aleph projects as rectifier bridges - take a look at this thread if You`re interested :
http://www.diyvideo.com/forums/show...8770#post328770

If somebody from this PCB-group buy is interested, let me know soon - I could hold back Your PCB shipping and combine the PCB shipping with diodes.

Hello everybody,

It wasn't too difficult to find the parts list ;) at the aleph wiki page.

But it came to my mind that we all will need huge transformers as well as decent heat sinks. Both items may be much cheaper when bought in large numbers.

If you are interested I could organize the group order concerning torodials and heat sinks (the heavy stuff) but CAN NOT do this for the transistors because I have no possibilities (as well as no glue) to measure/match them. :no:

I can imagine buying heat sink chassis, too (look at www.schuro.de for example). What size of heat sink and transformer will be needed? :scratch1:

Cheers
Christian.

Concerning FETs:
Reichelt states 1€20 (incl. VAT) for IRFP044, wich ist by far the best price to get.
IRDirect states 1$81 (plus txes, shipping, toll) in quantities below 1000 pcs.
Farnell states 3€70 (IRFP044N, plus VAT) in quantities below 1000.

Me also would be interested in heavy duty, high quality torodials group purchase but I think there are two serious issues with this:

first: I believe the different transformer power and secondary voltage rating needs for each individual XA-builder will vary too much. Usually You can get good prices only for ONE specific model - not for 5 ore more different versions.

second: a torodial transformer group purchase would only make sense when the tranformers could be shipped directly from the factory to each participant of the group purchase - what I doubt is possible. Otherwise the costs for shipping and reshipping this heavy stuff very likely will eat up the savings due to the group purchase.

Great idea, as we need matched FETs. Buying a reasonable lot (Reichelt?) and getting the selection process "centralized" could help a lot.

I`d be in in buying a reasonable lot but I doubt that anyone has the time to match a couple of hundret groups of FET`s out of a couple of thousends lot.
We have 200 boards here - if each is stuffed only with the minimum 4 FET/board - that`s 800 FET`s minimum - to get such an amount of matched FET`s I guess we would need estimated 1000 pcs. minimum (from same batch/manufactorer).:eek:
Thoroughly matching suitable groups of FET`s must take weeks (don`t forget that each FET should settle in temperature before making reliable measurement) - I seriously doubt that anyone has the time (not to speak from patience) to do this.
I believe, to achieve this in reasonable time without a special (semiautomatic) test rig which can measure a lot (say 50 pcs.) at once is quite hopeless.



BTW: I begin packing PCB`s now and hope to be able to ship out tomorrow

Hello,

I am not too sure that we would not save money by group-ordering the heavy stuff despite the additional shipping costs.

There are reasonably offerings from 10 pcs., so we could offer e.g. two different torodials.

Concerning the Transistors: I thought the person who will match transistors for a number of interested people will get a fair payment for doing it.

Regarding transistor prices: I would not like to order at reichelt. Once, I ordered a dozen TL431 and got three different types! (different manufacturers as well as TL431A, TL431C ...)

I also would wish to order everything from ONE or maybe two suppliers just to keep it simple. In the case of everybody is ordering her/himself shipping cost is another issue.

But even in this case we could share ordering numbers ;)

Cheers
Christian.

Well, I would. The trick is to tell them that you need components from one manufacturer, and, if possible, from the same production lot. Proven strategy :D

Hallo Holger,

nice strategy indeed. Thanks for sharing...

Dear all,

May I add my 2 cents worth to the discussion.

I bought 100 IRFP044's (not 044N's from Reichelt) indirectly from IR, all from one wafer lot (with luck, was no guarantee), matched 25 of them during Christmas, picked 4 (not the best) and bulit a standard Aleph-X using Grey's schematics but with 1A bias per transistor (source resistor 0R47) and cheap parts from Reichelt otherwise just to test PCB, etc. Power supply was just standard bench supply from Reichelt. The 9610's were also from the same lot, matched at room temperature at both 10 and 20mA. I took again a pair at random.

It ran first time without trouble, no swapping, nothing; actually too easy as I don't know what else trouble to expect if I were to go for a higher power version. At startup absolute DC on both outputs to ground was about 2V, dropping to around 0.2V after 30 minutes. Differential DC was never more than 20mV and most of the time around 2mV. Transistors were matched at working current and temperature (put them in the oven first helped).

So obviously the matching was OK, but I am currently trying to develope a method to test entire curve from 0.25A to 1.5A, with reasonable effort. It would take a while (unlikely before Easter) but if it works, I would be prepared to offer the rest as matched sets (of 4 or 8) at a reasonable cost (believe me, you would never be able to afford my salary, so I am just doing this for fun and not for money) after I take the first 33. If someone lives nearby (east of Stuttgart) and volunteer to help, he gets to choose the next set of 8 at cost.

In a blind test with 6 people, including 2 amateur musicians, the AX, as it is (8W), came out on top, slightly better than JLH 15W (2 amps driven as differential through a phase shifter, see JLH Letters to the editor 1970), and both beat my Krell KAV300i by a distance despite lack of power, and hence base control. Female vocal was particularly the strength of AX (Shirley Bassey came to live 1m away). So I am totally convinced. Thank you very much Mr. Pass.

For one or two amps, most components one can find from Reichelt, Schuro, or Farnell, be it more expensive than if you buy 1000 from a distributor. For me, the one component I am having most difficulties with are the 3W source resistors. Of course you could use the MOX 4W from Intertechnik (which is what I use for the prototype), but I would love to try Vishay Dale CPF3 metal film. Under 1 ohm, they are next to impossible to get ex-stock. Minimum order quantity is 5000, and I guess they would cost around 20 Euro per hundred at that quantity, plus post plus MwSt. I want to use 0R39 instead of 0R47, to give it a bit more bias (see Nelson's article on matching) at 20V rails. My heatsink would be large enough to give 15 degC rise above ambient. If there would be sufficient people interested (say 50 people and everyone take 100) so that we can get to 5000, I would be prepared to do all the ordering and accounting, etc. Unless someone else would volunteer, to my greatest pleasure.

The other alternatives would be :

a) to use MFS3 5% from Welwyn at around the same price with 600 minimum,

b) to use 3 x 1.2ohm 2W 5% in parallel from Reichelt, which would cost 27 cent and give you better tolerances at the same time, at the cost of a bit more real estate on the PCB (probably won't all feed onto the standard board.

My preference at the moment is still Vishay, so please let me know if there is sufficient interest for a group buy. Don't send me emails please as I would have no time to check them all and you would be keeping me from my matching activities. Just post to the forum and I shall check every now and then when I have time.

The rest is difficult to do together, as people might want to use different rail voltages and different number of devices in parallel.

One thing to watch is the power supply capacitors. If you intend to use CRCRC, say 44000uF as C and 0.22ohm as R, you would get more than 35 amps peak charging current, which equates to some 15A rms, for the first C, very close to if not exceeding the maximum rating (for 3000 hours) for most large caps. So you might wish to consider parallel small caps (say 20 x 2200uF) through current balancing resistors.

There are enough threads on the forum on rectifier diodes, input caps, etc., so I am not going into that.

I always buy the IR Mosfets from www.schuro.de. Never had a problem from there.
HBarske
The problem is, considering for example IRFP240: 2€31 (Schuro) vs. 1€35 (Reichelt).
bertram
Patrick,

I live nearby (Schorndorf) and will help you with matching although I also have heavy time constraints. You can mail me to fix the details.

Bertram

P.S.: I will need more than only 8 FETs.
cocolino
and I´m glad it`s (almost) over :)

Yesterday I have packed almost everything (unless two people who have requested to still hold back their boards) and shipped out today (as at Saturdays the post office is extremly crowded anyway the officer wasn`t exactly happy that I caused an even huger queue).

So I hope that everything arrives well :xfingers:, I think everybody should get his boards before the next weekend at the latest (most will arrive earlier).


So I wish all of You much fun and good luck with Your projects and ......let`s show Your works!!:djinn:

Christoph (Coculino),

Ulrich (who is a colleague) from Ulm has ordered 10 boards. He just left Friday for Thailand for 3 weeks' holiday. If his package bounds back from the post after one week, you know why, and please hang on to it and send him a email.

I don't have authorisation to fetch his post, and his lives 80km from where I do, so there is little I can do.

Sorry for the trouble,
Patrick

To those getting their new AX boards.

If you're a Cardas fan, the 2nd annual Cardas bulk purchase is just starting to pick up steam. If you're interested see this thread in the trading Post Forum and the WIKI Page for details.

I have already sent 100 price lists out.

Hi Christoph,

Sorry to spam you like this. I'm sure you'll understand.

Thanks Patrick - good to know!
Ulrich`s board where shipped letter post (uninsured - so no need to sign anything) and in case they fit in his mailbox there will be no problem.
If it bounce back though, I`ll keep it until Ulrich is back and I`ll email him.

I hope not more of You guys are in Thailand (though I can understand this well:D ......the weather is just too fine there;) ) I was so glad to get all the stuff out and I wouldn`t really want to see coming half of it back:cannotbe:

Rodd,
no problem at all here.........in fact...I really appreciate all the bulk purchase things and other offers that are going on here increasingly.....there is no better way to save on money!

.... and actually this is a good opportunity to place some spam myself:angel:.....

Folks, I hope You don`t really mind when I draw Your attention on this thread again:
High-Power, High-Voltage Dual Schottky diodes for sale
I have already lots of requests and orders from all over the world (and as it appears I`ll sell all of them) but oddly enough none from Germany what makes me really wonder - so much X-Aleph boards...:scratch:
I believe You won`t find anything better (and more handy than those) at a better price.
Now that`s enough spammed.:smash:

Hi Christof
I Think its because Hexfreds are hip at the moment in this Area .

Anyway I would like to try these ones. Please send me a mail about the cost of 12 Pieces whith Porto. Same Konto as The Boards ? I transfer the money when I got your mail.

Regards Bernhard


PS: Der Plan is: Teile sammeln bis ich die Amps bauen muß ;) ;) ;)

Hi Bernhard,

I wouldn`t say hip - this sounds too much about fashion.

Take a look what the experts have to say about this.
Looks like this is much more than just fashion or even hype:

Hi
Got my Boards also, Thank you very much:) :)

They are looking very good and very inspiring. It seems that I can hear sweet Sounds when I get my Ear very close to them:angel: :angel: :angel:

Hello everybody,

I went to the post office yesterday and am amazed by the quality of these boards! Thanks a lot!

Now, if there is somebody around Dresden who will solder he/she might contact me.

Apart from this, I would appreciate if anybody could offer matched transistors to me. (here or by private email). Of course, I am willing to pay a certain amount of Euros for that...

Cheers
Christian.

Hello all,

can someone tell me where to find the latest schematic with all the caps?

parts list available somewhere?

Happy to hear from you!

Not an elegant question:

Is there anybody with a redundant PCB pair? Maybe bought for safety and now surplus?
If I had a chance, mail me please. Would be sent an deutsche Adresse.

Thanks in advance,

I received as well the boards as promsed, great stuff, Thanks a lot again !
