Ryssen
The Pcb is this one http://www.diyaudio.com/forums/show...852#post1071852
And the link in the same post shows the original Symasym 5,3.
So the board is the Symasym 5,3 and this power supply http://www.diyaudio.com/forums/show...226#post1147226
on the same Pcb.
This is the zip file with the board files:http://www.diyaudio.com/forums/atta...tamp=1171216158
I´ve made a xls sheet with those signed up so far,if you are interested
tell me in this thread and i´ll sign you.
If somme one want to make a Wiki page do so,I am not experient enough!
Please make correction if so.:)

How much for shipping inside EU? Thanks, Markus
Ryssen
2 original Symasym 5,3 boards in this paper envelope is
60g.

So 2 of the AAK boards will probably be under 100g.
The envelope is 10SEK = 1,39$ (Using forex)
100g inside EU is 20SEK = 2,79$
100g outside EU is 25SEK = 3,49$

4 boards will be up to 250g
250g inside EU is 40SEK = 5,58$
250g outside EU is 50SEK = 6,97$

Shippig from Pcb maker to me,if 30 boards ,162,50SEK = 22,66$.
Is devided with all boards.:angel: :cool: :)

Here's a compilation of the information available from Symasym - the sequel thread to help in building my board. Of course I'll be around and open to all question to make sure the assembly process goes as smoothly as possible.

So...what is the board set price? What would the total be for boards and shipping to 21601 in the U.S.? USD if possible.

Thanks!
Ryssen
If we buy 30 pcb´s the price for one Pcb is 19,12$.
30 boards/22,66$ = 0,76$ /board.(shipping boards to me)
The envelope is 10SEK = 1,39$
Depending on how many boards you want,just calculate with the shipping prices in post 3.:)

In my pricelist it just says,inside EU,and outside EU.
So I don´t think it matters which state you live in.

If whe buy more than 30pcb´s might be a little cheaper.
RKH
I'd be in for 2-4 if this GB comes through.
Ryssen
Of course it will come trough.:cool: :)
So you want 4 boards?Shall I sign you up?
Please send me your adres in that case.:)

OK I made up my mind... and I am in for 8 boards. Trying to be future-proof... Maybe we can get this up to 50 or whatever the next price point is for economies of scale! Ryssen, will PM you with address details.
Ryssen
Now uppdated! 50 boards..:bigeyes:
jinkslynx
Four boards to me please, also any chance of an updated BOM for this board and a recomandation on where to order the parts :)
Ryssen
Uppdated 54 boards.
I belive this is the last one http://www.diyaudio.com/forums/show...039#post1085039

If we set the last date for signup to 31/3,will that be okay?If anyone have anything to say about this please do!:)
johngalt47
That's fine with me.

Hello,

I was thinking about building this amp for a while. Seems like it's time to act.

Sign me up for 4 boards, please.



.
Ryssen
I will!
Can you send me your adress?
I will uppdate the xls.
bmordue
hi,
I'd like to buy two boards please.
Ryssen
Updated!
I have to update the adress to the xls.since we got a new adress to the server in sweden..
http://bildarkiv.hififorum.nu./Ryss...AK%20modell.xls
By the way AAK and SteveA got any adress to send me yet??
sandro600
Can we still sign up for boards ? if so 4 boards for me please.
Ryssen
I´ll sign you up for 4 boards,send me your home adress,so my work wont be so heavy later on..;) :)
Ryssen
On monday the 2/4 (31/3 is a holliday)I will send the final order,and ask for the final price and write the final price in the xls,file.the prefered method for pay ment is Paypal,temsa@beta.telenordia.se but some can´t use it and will use banktransfere,I will send info by e-mail.
But the BIG issue here is Steve A and AAKwhom I asked 2 or 3 times to send me the adress,both in the thread and by e-mail.If your interessted in this group buy,could you please send me the adress to confirm so..I don´t think I can afford to order your board,if you don´t want/need them,I don´t need that many boards.Or if we should wait for you I don´t know..
Ryssen
Ok,they are still dropping in!74 boards now!Got the adress from SteveA,thanks.If anyone knows AAK,drop him a line to let him know..:)
lsinclair
Can I sign up for four boards? I will email you my address.
lsinclair
Ryssen - I can't email you as I'm a noob and still under moderation - please can you email me for my details? Thanks
Tolu
@Ryssen

Sorry, but do I understand right that one PCB is only 0,76 Euro? Cheaper than the post charge?

Then I want 2 boards!

I can't send you a PM because I am a newbie and still on moderation!

Regards

tolu
Ryssen
Isinclair and Cobra2 added to the list.
Tolu my e-mail adress is:temsa@beta.telenordia.se
The last time I askedCopra Pro AB the price was 19,12$ a peace if we ordered 30 boards,so it is probably less now that we have 76 boards now.I think it is low enough anyway,Tell me if you want PCB´s and i´ll set you up.

Been thinking:bigeyes: as there seems to be people wanting boards even after this last date,I´will let this thread be open and take signups for boards after this run.:) As I don´t think we/I can delay this one any more.

Åke
Ryssen
Ben doing som heavy calculating tonight.:cool:
I have made the order,and was told that the boards would be delivered to me when they recived the payment.
One Pcb inkl.shipping to me is,86,25SEK = 12,12USD.I have calculatetd
the sum ,"Final sum inkl, 5%paypal" please chek if you like.. that is the amount that is to be payed to my paypal account,(I will mail the Swedish fellows..)my paypal adress is: temsa@beta.telenordia.se once the payment is recived I will mark that in this xls. Final payment Please sign the transfere with your nickname.
I will send MBK my bank details.

4 more payments to go..:)
It just stroke me:

Supply

It says 50vx2 out from the supply,the orginal is 36vx2,is 50v the right supply for this modell?Will 300VA be enough for 2 channels?
MBK
I guess it al depends on how much "overkill" one is willing to finance in DIY... Most commercial class AB amps have their PSU's dimensioned far smaller than nominal RMS output power because constant full power output is rare. 50V rails minus say 5V drop should give continuous 125W into 8 Ohms if the heatsinks etc. hold... This times two means that nominally a 300 VA PSU is certainly OK for 2 channels. I will use 250 VA for 36V rails.

I have some questions too, about the BOM mostly: discrepancies with the original that are not related to thermal stability for instance etc. Maybe we should either, move the discussion of these matters to the original thread, or create a "AAK Symasym builder's thread" as customary...
jaybombalous
Has a new date been set for more PCB's to be made? Has there been enough interest shown to get another buy going still?

Thanks in advanced.
Colescuttle
Isn't it true that if your transformer delivers +36/0/-36 AC you will get roughly +50/-50 DC rails, depending on the efficiency of your diodes?
Ryssen
quote:

No new date has been set,but we can do an interest check,If you are interested,tell me how many boards you want and I´ll start a new list.:)
quote:

Yes,it´s true.2x24v AC will get ju about 2x33v DC.
2x26v AC will get you 2x36v DC.
But I don´t know,I read in the Sequel thread the 50v gave less distortion.Maybee the konstruktor can tell if it´s so.
Well maybe it´s a god idea to start a new thread about this,anyone would like the plesaure of doing it?:wave:

Hi Ryssen,

How much will be the shipping cost to Hong Kong for 2 boards?
Ryssen
So 2 of the AAK boards will be under 100g.
100g inside EU is 20SEK = 2,79$
100g outside EU is 25SEK = 3,49$

4 boards will be up to 250g
250g inside EU is 40SEK = 5,58$
250g outside EU is 50SEK = 6,97$

2 boards,and Hong kong is outside of EU,;) so 3,49$ depending on the
current excance rate.:)
Ryssen
Second run
20 boards and rising..:)
