Hi All,
those lucky enough to to soon be receiving one of Pedja's 1541A DAC pcbs might be interested in this GP. I have had a quote from Airlink Transformers for a custon-wound toroid for this DAC. I specified potting and banding. Hopefully dispatched to you direct from the factory.
Here is the info:
I am looking for a quote, please, on a specially wound toriodal
transformer. I have been part of a DIYAudio group purchase for some 1000 VA toroids about 9 months ago, and will hopefully be able to get 10 plus orders for this particular spec. The application is a high-quality Digital to Analogue converter and the windings are as such:
Transformer TR1 secondary windings
#nominal voltage current rating actual circuit requirement
1 7-9V 1A 20mA
2 7-9V 1A 13mA
3 7-9V 1.5A 27mA
4 7-9V 1.5A 37mA
5 21-22V 2A 40mA
6 17-18V 1.5A 15mA
7 17-18V 1.5A 15mA
8 7-9V 2A optional, for a reclocker
The 7-9V seconadries I would like to specify as 9V. The 21-22V as 22V, and the 17-18V as 18V.
In summary, five secondaries of 9V, two of 18V and one of 22V. I would require the toroid potted and banded as well, please.
No rush on this. I would appreciate if consideration be given to
dispatch to individuals ex-works. I will coordinate payment and
dispatch details.

Thank you for your enquiry and have pleasure in submitting the following
quotation:-
Part # 8267 160va 230v 5x9 2x18 £64.47 - FOR ORDERS OF 10+ CAN REDUCE TO £30.62e.a.
Should you require any further information please do not hesitate to contact me direct,
Kind regards
Airlink Transformers
So, what do you think?? Can anyone improve on that?
Cheers

Do yourself a favour and stay clear of Airlink transformers. They have extrordinary bad service and a real bad relation to warranty issues and specs. As soon as you've paid, any problem that may occour....is your problem, they don't care. I fought them for several month over a couple of errors obviously made by them, which they didn't want to correct.
This is the general attitude of Airlink, not just one careless person.
There are other transformer manufacturers in the world, no reason to support a company that behaves like that.

Hi Jon
Just set you a PM to see how you got on sourcing the transformer. I'm in the UK and need one.
Dave |

Dave,
you have mail.
Is there anyone else in the UK that is interested in a custom-wound trafo? I have been a bit tied up recently, so soucing this part has slipped below my horizon.

not in the UK but also interested in one of those transformers,
or even two of them - (I'm trying to talk a friend into this project) :cool: |

Hi Magura,
cast your mind back to 5th Oct....... ;) I haven't had them chase me to follow up the quote, mind you. :angel:
A decent supplier at the right price would be excellent. I'm more than happy to try another couple of local companies for quotes. With the GBP and Euro so strong against the USD, it might also benefit us to look further afield than the UK or EU. If anyone has any suggestions, please feel free to list them. I have emailed Plitron and VM and we'll see what they say.
I have also just had a spending moratorium strongly suggested by Mrs C, and I have agreed to it. Therefore my limit is somewhere around 50 Euros (slush money) for the trafo - unless I can do some window-cleaning on the side!!! :D
Cheers
Jon |

Antrim have called me to confirm the spec and will be quoting in a few days - got 10 prototype orders in front of ours.
They will be more expensive than Airlink, but I believe the trafos will be quieter.
More as it comes.
Jon |
|

Nice one Jon, keep us updated
My dac has been up and running for a few weeks, I'm currently using separate transformers but a single one would be better
I'm also struggling for a case, the dac and transformers are bolted to a piece of wood

How many trafo's do you need by now??
Magura :) |

I'm in for one as well.
Dave |

| jonclancy |
Errr.....not quite sure. About 6 or so at the moment.
The quotes are all designed around the 10+ unit price break.
Antrim are going to email me the quote - I assume VM and Plitron will do the same. Not expecting anything for a few days though. Sadly no longer have access to a computer midweek, so I'll update at weekends.
Cheers
Jon
PS How does your DAC sound? I have been a little side tracked with the TX102 stuff, so need to get on with this project soon-ish. |
|
|
| t. |
Hi Jon,
The dac sounds excellent, to be honest I can't fault it:)
The BG caps take some time to burn in though.
All the resistors in the signal path are Caddock mk132 apart from the 1k5 for the AD844 which is Caddock TFO20, I tried Rikens in that position but I much prefer the TF020.
I also use the discrete buffer instead of the AD844's internal one and the dac chip is TDA1541S2 |
|
|
| jonclancy |
Now that is very encouraging!!!! :cool:
I know what you mean about the BGs - my DACKit is still improving and I've had it going for ages.
Cheers
Jon |
|
|
| jonclancy |
OK, I have received the Antrim quote. No word yet from VM or Plitron. All prices plus VAT. The more expensive trafo is the encapsulated version.
Pse have a close look at this spec to see if I have missed anything - It looks pretty good to me. The postage of 25 GBP plus VAT to me and onward post AND packaging looks like a false economy when you can have your trafos delivered to your door for 7.50 GBP.
I am considering paying for a prototype to test with one of the DIYers who has got his DAC up and running, before we go firm on the order - if that is the way it turns out. Any comments?
Have a look and tell me what you think....... Anyway, here is the info:

I would be in for 2 pieces of the 1st type (GBP 35,-),
which ones are you considering
regards Henk
PS still have my PCB's lying here as I got them from Pedja. Have most of the components waiting as well as the S2 dac's. The trafo's and some caps are missing. Can't wait to hear the sound of this class A design |

Hi Henk,
I am considering the more expensive encapulated version. There is also a WIKI on the componenjt parts for this DAC - when I do my ordr at some stage inthe future, I'll place the part numbers in the WIKI. If you have some good thoughts about a particular component, please place details in the WIKI. This is just to help newcomers like me to select parts of a quality to match this DAC.
I too have an S2 awaiting!! :D

Hi All,
diyAudio user Lupulroz has kindly offered the following: :)
> Hello,
> if it's any help - I can do your transformer for 25 euro + shipping.
> I made a lot of custom requests for diy-ers from the forum.
> Orientative prices at http://www.rockna-line.com/toroids.htm
>For potted core & mounting kit included price is 30 euro / piece.
>Shipping to UK for 15 pcs. (approx. 30 kg package) is 140 euro.
Shipping to a single UK destination is the same price as would be for individual delivery from Antrim in the UK - so there will be additional postage to pay. I can see how much a 2kg parcel will be for the UK and EU. Don't forget to add VAT to all prices quoted in this thread - UK Customs will add it to any imports and it will be charged by any UK-based company.
Have a look at the Rockna site, have a think about the sums and let me know your thoughts.
Cheers
Jon |

Hi All,
the limited feedback I have received points towards the Antrim trafos. Prices are more than the kind offer from Lupulroz, but the advantage to me is that I don't have to re-post an order to all involved.
I'll get a WIKI up tonight. The spec is for an encapsulated trafo. Shipping will be ex-works to your door. I'll have a word with them about how we are going to pay. For EU buyers, we can come to an arrangement using PayPal perhaps.
I'm not intending to order for a week or so - just to let the numbers hopefully rise. We need at least 10 to make this work.
Cheers
Jon

Hi,
I just got this reply from Antrim. I did alter the secondary out positions to match the PCB (so secondaries weren't crossing etc).
I am awaiting the updated price from Antrim and, if I get it tonight, I'll post. Otherwise, please bear with me until I can get to a machine with internet access.
Here's what I wrote:
Secondary Windings:
Amendments to secondary positions to suit PCB – ratings unchanged.
0-18V @ 1.5A rms (red-yellow @ 3 o/c)
0-18V @ 1.5A rms (blue-grey @ 3 o/c)
0-9V @ 2A rms (violet-violet @ 3 o/c)
0-9V @ 1.5A rms (green-violet @ 6 o/c)
0-9V @ 1.5A rms (orange-pink @ 6 o/c)
0-9V @ 1A rms (red-yellow @ 6 o/c)
0-22V @ 2A rms (green-green @ 6 o/c)
0-9V @ 1A rms (blue-grey @ 9 o/c)
No connectors or flexible leads required, thank you.
Please confirm quotation is extant. Will there be an extra cost to ship to Germany (one unit, 2 units, one unit), Netherlands (2 units) and Norway (one unit)? Also, one UK order is for 2 units). Will you be able to supply the Norway unit ex-VAT? Many thanks. Jon Clancy
Jon,
Thank you for your order, I am currently sourcing posting to Europe, the best way is with royal mail I just need to get prices.
I have attached an updated quotation which has taken into account you desired leadout positions.
Terry our design engineer asked me to point out:
Please note that as the two 9V @ 1A secondaries now exit at different positions they can no longer be bifilar wound, therefore these secondaries now count as two windings rather than a split winding which means that the prices have increased.
Also note that I have swapped the colour codes for the two 2A secondaries to avoid green leads from two separate secondaries from exiting at the same postion.
IF you are still OK with this price drop me a quick line and will get them in production,
Thanks
Jon :) |
|
|
| Michi124 |
In case Blitz and curva agree, I would suggest to have all the transformers that go to Germany sent to me,
being forwarded to them thereafter. Shipping costs should be somewhat lower then... |
|
|
| curva |
| I agree... thanks for helping out :) |
|
|
| jonclancy |
Hi all,
I have just spoken with Antrim.
New price because I moved the secondaries around is 37.18 plus shipping plus VAT.
Noted that the Germany orders will go to Michi124. Antrim will commence production and will give me a call when the trafos are almost ready. The will ship then invoice me. I intend to pay on CC and will then ask for payment from you guys. More details will be added to the WIKI. I'll close it this weekend.
All for now - update Thursday evening if I have any more info.....
Cheers
Jon :smash: |

| UK Dave |
I've been a bit busy recently, but glad to see Jon has made such good progress.
I've added myself to the WIKI.
I've had a quick look at the thread and WIKI but can't see how you want payment. Don't worry replying if it's in there somewhere, I'll dig it out when I get more time.
Jon - I owe you :drink: for all the effort you've put in (and lack of it from my part).
Dave |
|
|
| jonclancy |
No probs, Dave.
Payment will be by direct transfer if in the UK. I can do PayPal for those outside orders. In fact, am happy with any method really, as long as my costs are covered.......
I'll give Antrim a shout to let them know the numbers will be frozen on Tuesday.
If you know of anyone who needs one of thse trafos, pse get them to email me, post here, or better, update the WIKI with their order.
Cheers
Jon :D |

| Has any one built this dac yet ? The Pedja Dac ? Any one got anypictures or problems with the dac ? Im planning on building one but there are problems no dac chip. They are not made any more. Are there drop in replacment's or Drop in chip boards that change the sop socket to Surfac mount. |

Yes, I've built one but using temporary seperate transformers.
I had no problems at all and I'm very pleased with the performance;)
The sound improves alot after the BG caps have had a good few days burn in.
If your struggling to find a supplier of the TDA1541A's its worth keeping your eye open for a cheap cdp that uses these chips.
There is no replacements for this dac |

Have a look for the old Philips cd players, theres a lot of different old cdp's that use the TDA1541A, you can just take it out and use it in the dac
Well I still need a case, mine is strapped to a piece of wood:D as soon as I get a case sorted I'll post some pictures |

Hi,
There are opportunities to get 1541As here on the forum. For instance, I got some standard 1541As to use while getting my DAC up and running. When I am happy that my workmanship isn't going to blow anything, I'll change the standard 1541A for an S2 I have stashed.
You could PM Elib (on these forums) - plenty of us have got 1541As from him, including your fellow Canadians, and I was very pleased with the transaction.

I haven't built mine yet - once I have my trafo sorted, I'll turn to component selection.
There is a WIKI for component part numbers etc. I will be putting my info on there when I go through the process - there's already a whole load of info that you might find useful.
http://www.diyaudio.com/wiki/index....=Parts+selction
Main thread is here:
http://www.diyaudio.com/forums/show...50&pagenumber=1
The S2 I was referring to is a grade of 1541A. They came in standard, R1, S1 and S2 versions IIRC. I believe the S2 were a later re-run for a high end CD player - was it the Marantz CD7?

I found the difference between the TDA1541A,S1 and S2 very interesting.
The S2 clearly sounded the best in my set-up, especially the bass
BTW your correct, the cd7 uses 2 x TDA1541S2's |

Hi All,
here is a quick update:
As you know, I made some minor changes to the trafo spec regarding the secondaries' positioning.
I had an email conversation with Pedja on the subject, and we discussed thus:
> > If the primaries on the trafo are at the 12 o'clock position (but the trafo
> > is then mounted turned through, perhaps, 45 degrees to the left), then can I
> > confirm the following secondaries at the 3 o'clock position?
>
> >>18VAC - 1.5A (analog stage)
> >>18VAC - 1.5A (analog stage)
> >>9VAC - 1A (CS8412 analog)
>
> > Then at the 6 o'clock position:
>
> >>9VAC - 1A (CS8412 digital + LEDs)
> >>9VAC - 1.5A (TDA1541A +5V)
> >>9VAC - 1.5A (TDA1541A -5V)
> >>9VAC - 2A (reclocker) - this may depend on the actual reclocker
> >>22VAC - 2A (TDA1541A -15V)
>
>Yes, that is it. Though my transformer has secondary windings leads

>
>
> > We don't need any secondaries exiting the trafo at the 9 o'clock position.
> > The re-clocker secondary would be floating until employed.
I phoned Antrim's technical designer and had a chat about the secondaries. They have been able to produce for us secondaries that exit every 20 degrees or so from the 3 o'clock position - the primaries are at the 12 o'clock position.
In effect, our trafo replicates the original that Pedja specified. The not so good news is that, as all the windings are separate and none can be bi-filar, the cost has risen again slightly to 41.15 (plus delivery plus VAT). I hope that no-one is inconvenienced by this small rise - I gave the go-ahead knowing that you all want to get a quality trafo that will install with ease.
Delivery details etc will be confirmed when Antrim call nearer to job completion.
In the meantime, pse will you PM me your real name and delivery address so I can draft a plan for Antrim. I will not disclose your details to anyone bar Antrim.
More info as it comes.....
Jon |

John,
I have no knowledge nor experience about the what winding techniques makes the best trafo. With all confidence I trust the trafo solution you described is the 'sound-wise' the best, and given that the price is no problem (for me). If it was I should have been building another DAC or no DAC at all.
Thanks very much for all your time spend on this project, which gives me the opportunity to get a trafo optimised for Pedja's DAC.

Hi All,
Some good news and some not so good news.
The trafos are all wound. However, they have had an ordering oversight on the encapsulation cases.
The 6 cases they have will have the trafos potted into then this weekend and will be ready for shipping midweek.
Here is the situation:
//////Quote
Hi Jon,
Hope you are well. I am sorry to say that we have encountered a small problem here. We only have 6 encapsulated shells left. More are currently on order and should be with us within the next three weeks. Now I have no problem in getting the ball rolling and sending the first six out next week but if you prefer me to wait and ship them all together I can do that too.
I am really sorry about this. I hope it does not cause you to much inconvenience .. Your transformers are made they just need to be encapsulated. Please let me know how you would like to proceed, even give me a ring and we can sort something out.
////////Unquote
As I see it, we should get the 6 shipped ASAP and deal with the rest later. I am happy to wait as I haven't built my DAC yet. What are your thoughts - Do we agree among ourselves who gets the first shipment, or do we agree to send out the Germany order (for instance)?
I assume that option X would be to take the trafos un-potted. I personally would prefer to await arrival of a potted version.
Finally, sorry to you all for this small glitch. If we are happy to choose a way forward over the weekend, I'll get the delivery arrange next week.
Cheers

Hi Jon,
Thanks for the update, I have no problem in waiting either seeing as though I'm using seperate trannies so there is no rush:)
Leo |

No problem Jon!
I can wait for the last batch, still collecting other parts so no hurry!

Thanks Guys.
Does anyone have a problem if Michi takes the first 6?
Let me know over the weekend.........
Cheers
Jon:) |

Thanks for the the offer Jon,
but four trannies should be enough for Blitz, curva and me
- this is the exact amount that we ordered...
I still need quite a few parts, so I won't be able to post results of the entire DAC
with the new transformer soon - but I'll certainly post pictures of the transformer itself.
One more suggestion: Since the delay because of the missing shells is Antrim's own fault,
they might be willing to pay for shipping of the first batch themselfes,
at least in part...
They could ship the other two trannies directly to Jon, for example... |

Four it is!! :rolleyes:

| I've no problem with the split as you suggest above, it seems logical that people who can report back earliest get first crack. |

Ta.
Any other thoughts before I get this plan arranged with Antrim?
I'll be ringing them on Tues AM, so let me know by then if there are any changes.
Cheers

any idea what should this babe cost shipped to me(in germany)?
how may I pay? paypal? |
|
|
| jonclancy |
Hi,
Antrim are going to post the order and then tell me exactly what is was and charge my CC accordingly. Michi was going to get the 4 Germany orders and post them on - should be a saving? If not, I can get them sent individually.
Payment will either be by PayPal in GBP or I'll see if I can get the IBAN for one of my accounts for direct transfers in GBP.
HTH
Jon
Sun's out today! :cool: |

Hi All,
The missing shells have arrived, so Antrim are going to get the trafos in the post on MONDAY!!! :D
UK Dave and Calimero - pse email me your delivery addesses.
I will PM you all back with payment methods and details based on actual shipping costs.
Have a great weekend! :cool:

I received this today:
Hi Jon,
I will be posting everything at the same time tomorrow afternoon. If you could please try and have all the addresses with me by then I would be grateful.
Just one address to go (Calimero) for shipment.
I'll email you individually this evening regarding payment arrangements. I won't know the exact total until Tracey returns from the Post Office.
Cheers

Guys,
I have just been comparing the trafo label with the colour scheme in one of my letters to Antrim.
The appears to be a difference in labelling. If the trafo label is indeed the order of secondary output, then the 2 x 18v secondaries are in a different place from where I specified, but no great deal really. If I go by the colour code in the old letter, then I am really confused.
Anyhow, please get a meter on your trafo before you connect it up. I think the label will be correct, but we need to be sure.
I'd call Antrim tech, but it's gone half 6 on a Friday eve.
To those connecting up this weekend, please keep the rest of us in the loop.
Thanks! :xeye:
Jon :confused: |

curva, you have disabled your email through the forum.
Please contact me, I also need your shipping address. |
|
|
| jonclancy |
Hi All,
Leo has measured the secondaries and they match trhe PCB. :lifesavr:
I have just emailed Antrim to confirm the current ratings are as specced. I suspect this is just a labelling error and I will get a pen-amendment issued to you as soon as I get confirmation that the current ratings are in the correct order (for the 9V secondaries).
Cheers
Jon |
|
|
| curva |
| that doesn't sound too good... can someone check the current ratings? |
|
|
| jonclancy |
Hi,
I should have an answer from Antrim tomorrow. I'm sorry about the confusion here - we'll get to the bottom of this ASAP. I am confident the label is wrong. Not great, but at least we caught it.
Cheers
Jon |
|
|
| jonclancy |
Hi All,
OK - I was not aware that Antrim policy is to label their trafos with the winding order - highest current rating first. This does not reflect the order in which the secondaries exit the casing.
I've learned something here......:xeye:
Leo has done some measurements of one of the transformers.
These are non loaded voltages
Purple + Purple 24v
Green + Green 9.87v
Grey + Blue 9.94v
Red + Yellow 9.94v
Pink + Orange 9.92v
Green + Purple 9.96v
Blue + Grey 19.92v
Red + Yellow 19.90v
Many thanks for the payements received - I'll work out a spreadsheet and send the final accounts out when I have them done.
Cheers
Jon |

Hi Guys,
I had chance to try the transformer this morning with Pedja's dac.
Before I go any further please remember to make sure that Purple + Purple is for the -supply for the dac board and the green is for the Reclocker;) because the Purples are on the end don't go plugging them into the Reclocker by mistake or it could take the diodes out
Any way, the transformer seems to be working fine, the secondary voltages have hardly even dropped on the loads so its obvious this thing has more than enough juice to run the dac.
As also noticed by Pedja and Gary the polarity of the secondaries for the Reclocker make a difference to the sound and its the same with this Antrim transformer so I'd recommend you try it yourself.
Unfortunately I cannot recommend which way is best because the pair is Green:rolleyes:
Thanks again to Jon for sorting this thing out for us, I now need to build or buy another case because the Antrim takes up more room than my multiple trannys:D

Hi all,
the trafos for Germany finally arrived here.
When unpacking the very first one, I noticed that the potting material was cracked in a 2x4 cm area between the center mounting hole and the purple/purple and blue/grey secondaries. Small parts of the potting material are missing, too. :(
I then checked the other three trafos, they are ok.
Still, on all of them the trafo windings shine through the potting in this very region and also stand out of it a bit. Therefore, some elastic sheet (rubber etc.) is needed underneath when mounting them to a chassis.
The trafos were rather well packed, so I doubt the cracking issue has anything to do with shipping.
Did anyone else experience cracked pottings? |
|
|
| t. |
Sorry to hear about that Michael:(
You can see a small small bit of the grey sleeve wire underneath mine but it is only slight and is all well insulated.
The packaging seemed to be excellent with plenty of bubblewrap and luckily mine arrived fine.
I've also had a lot of bad experience with certain things being transit damaged lately:mad: |
|
|
| jonclancy |
Hi,
I've had a look at 2 of the 3 trafos here and there is no cracking of the potting material. There is slight chafing on some of the secondaries, but nothing too bad. I am intending to send the best two to Edgar and Rob, and just wrap a bit of insulating tape around mine to be sure - you can't really see if the sleeve is breached, but I am more than happy to run with this.
Michael, are you able to accept the trafo in this condition, or would you like me to raise the issue with Antrim?
I am pleased that the trafo is performing well. If there is a subsequent order, I will recommend that a second label listing the order that the secondaries exit the case is included as well as the electrical labelling. I'll also recommend that the colour code for the reclocker circuit is altered - but I suppose YMMV with whichever polarity you use, so you could just mark one line and try them out.
Leo, has the sound changed at all?
Cheers
Jon |
|
|
| t. |
Hi Jon,
Yes, I'd certainly say the sound is different compared to my multiple ones, there seems to be more bottom end with the Antrim and the sound seems slightly more solid but the dac is now on a piece of wood instead of the case as well.
Changing the polarity does make a very noticeable difference for the Reclocker, I tried it several times, its really strange to be honest.
I wonder if changing the polarity for the other parts of circuit makes a difference:bawling: |

Hi all,

Same with me.
I wouldn't want to hand out this damaged trafo to Blitz, curva or my Berlin friend, who gets the third one.
This means, I would have to keep this one for myself.
Do I want to do so? No.
Antrim was chosen as manufacturer of the trafos because they promised us very good quality
for a rather high, but reasonable price
- and not acceptable quality for a bargain price.
Therefore, I would really want to send this trafo back.
Let us email for details. |
|
|
| curva |
| Michi, I just wanted to say I have no time for finishing the DAC now and the way I see it it will take me another month to find some free time. Please consider the damaged trafo as mine and send it back in my name. For the money I won't take a damaged one, sorry. |
|
|
| jonclancy |
Fair enough, Michi.
I have emailed Antrim, and will let you know how we will take this forward.
Please bear with me for the time being.
Jon |

Hi,
Antrim rang me first thing this morning. They are very disappointed that this damage has occurred. They have stated that it would cost an absolute fortune to do a one-off replacement and that they had reservations about sending Calimero's parcel vial the post office today and not by their usual couriers (v. expensive). We are going to make an insurance claim against Parcel Force, :rolleyes: I will send Michi the 14th trafo that I had put aside for Rob Shellard. I have discussed packing methods with Antrim and they will mark Calimero's box as fragile. I am willing to take the risk with Parcel Force again as I didn't want to have them shipped to me and then on to NL as the cost goes up and there is twice the chance of damage in transit.
So there we are: in sum, spare to Michi at the weekend, Calimero's in the post today.
I'll be posting Edgar's today and will make sure it is well-packaged!!
Cheers
Jon |

Jon,
appreciate your efforts put into this GroupBuy very very much.
I am convinced that you and Antrim do everything in your reach to make sure the trafo's reach there destination without damage. The fact that despite your preventive actions, a trafo did damage, should not IMO result into financial implication for you. We should wait what your claim against Parcel Force will result in.
However ahead of that result I want to raise the question:
'How to solve situations like this that problems with delivery of the ordered stuff, result in unexpected costs.'
I take the view that I am aware of those risks and taken into account the organizer of the Buy has no intention to profit from it, all members that take part of of the Group Buy carry those risks and therefor there financial implications. That implies in this case I consider it faire that (possible) extra (delivery) costs made for the replacement of the trafo, are devided over the members.
I wonder what the standpoint is of other members in this buy.
Henk |

| jonclancy |
Hi Henk,
Thanks for your thoughts. This is one of the drawbacks to running a Group Buy. However, it does allow us the advantages of bulk purchase or cost-effective custom items.
As the claim against Parcel Force goes through, I will retain the financial risk. I accepted that risk at the beginning of the GB and hopefully PF will reimburse me all costs.
If it goes wrong, and I am out of pocket, then I would not expect a bale-out as I did not state that as a condition of the GB. Howerver, if this does happen, then any help will be much appreciated!! ;)
As we stand at the moment, this is a glitch. Antrim are very keen to help resolve the situation and are following up the claim.
Henk, your parcel is en-route. I am just going to post Edgar and Michael's now. Please check for damage when you take delivery This will help us to claim for any damage done.
Michi, I have inspected the 2 trafos I have here - you will be receiving the bestr of the two. There are minor chafing on a couple of the secondaries, but nothing major. The potting is level, no wires showing and no cracks.
Fingers crossed we get this sorted out.
All the best
Jon |

Edgar and Michi - I have just posted your parcels.
The Post Office would not accept them unless I gave and alternative address or return by surface if delivery could not be completed.
Can you ask your neighbours to take delivery of the parcel if you are not in?
Cheers
Jon |
|
|
| Michi124 |
Hi Jon,
no reason to worry. If I'm not in and no neighbour is available, parcels will be held at the nearest post office for seven days. That's the big advantage of Deutsche Post against all parcel services...
Many thanks for all your efforts to sort this out! |
|
|
| curva |
| Michi, I wrote you two emails and got no reply thus far... have you got them? |
|
|
| Michi124 |
curva,
the replacement trafo from Jon has not yet arrived. :(
Initially, it was my plan to wait for it and compare all trafos then.
On the other hand, I now have three trafos available
which are in good condition and fully usable.
I'll send you one of them to put an end to your wait...
Payment instructions are on their way by email. |
|
|
| jonclancy |
I believe it'll take around 10 days.
A good parcel service is not what we have here!!!
Jon |

Hello Jon!
The trafo finally arrived today!! It looks verry good! cant wait to put it to use.
Thank you for doing this GB, and also for including us non UK'ers even if it was a little exstra work.. :)

.. I was starting to get worried!! ;)
Make sure you let us know how your DAC turns out! :cool:

I got this thing today... looks like my neighbour took it on friday for me but she was gove over the weekend so I got it only now.
Looks good. No time to install it now, but I hope it also works ok. |
|
|
| curva |
looks like I finally found some free time to put this to work...
how to wire the primaries for 230V operation? connect black and white together and mains to pink and brown? |
|
|
| jonclancy |
Hi Curva,
That is the way I read the label.
Can someone please confirm this - I haven't done any mains powered projects yet, and so don't feel I have the experience to give advice here....
Cheers
Jon
PS, Parts order is in with Mouser - slowly going through the rest of the items. :) |
