I will offer the final test PCB up for sale (without 1541A chip), if your interested please send me your bid.

Starting bid will be $169 AUD (Cost of parts+PCB). Postage cost will be calculated for the winning bidder.

I will accept bids until 15th July.

Happy bidding!

IMHO this thread should be in the Vendors Bazar.

Hi Ryan
Question, are the shunt regs on the dac board already or ????

 

[ryanj]

Yes indeed they are.

 

[sumotan]

Aaaah nice.

This is a nice looking board, great job Ryan.
Couple questions, what is your preferred output stage with this ?
Also, is there a schematic for the 26V floating raw supply ?
Tia.

Hi,

Thanks.

My current output stage is the CEN passive IV, which ive been using for a while now.

The 26V supply is fed by a capacitance multiplier using darlingtons in both the negative and positive lines. Attached schematic is similar to what im using right now. R2 was just to simulate the load.

For the +5V supply im using ecdesigns "charge transfer supply".

Thanks to all those that have ordered and promptly made payment. I will start packaging the orders this weekend and send them out on Monday the 15th.

Hi! Does it make sense to use multiple boards? And how actually does it sound? I was looking for a 1541 project and run into this thread. I understand it is connected to another huge thread (ultimate nos dac tda1541a). I have no chance to read it even briefly.
Am i on time to order pcbs?
