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...

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.

50 V rectified?

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?

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.🙂

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?

Hi Ryssen,

You should of received payment via paypal yesterday from email address regaliatech@yahoo.com, instead of alsaudiokits@yahoo.com. I changed the address a few months ago and forgot about it, my mailing address is still the same.

Thanks,

Al

 

[Ryssen]

Updated.🙂

Cobra2?🙂

 

[Ryssen]

Updated the Run 2 today.

Payed Cogra Pro AB for the boards today,so within 2weeks I should have them.

Cobra2?

 

[Ryssen]

No signs of any boards yet,when they arrive I will post some pictures..

Cobra2,left for good?

 

[CeeVee]

Signed up for 2 Boards

Hi ...been thinking about building this for a long time, got here just in time it seems, sent you payment for 2 boards.

TKS

 

[Ryssen]

second Run
CeeVee your on the list!
To late for first run though.

 

[CeeVee]

Thanks,

I'll send you an email with the details, payment will take aa few days as i'm waiting for replancement of my credit card and i want to use paypal, but early next week i should be able to do it.

🙂

 

[Ryssen]

CeeVee thanks for the adress.And I´ve put you on the Second Run list!But wee have to wait until more people wants boards before making any payments,or else the pcb´s will be to excpensive.

Lets hope more people wants boards..🙂
