BTW: ..been looking for the schematic on this one, has anyone successfully built it? with the inclusion of the PSU on board, quite compact!

Hi abetir. I just want to help spread the sonic pleasure of SSA. Thanks.

The awesome PCB by sir Alex is Nico's version. You can see the schematic here:- Nico's SSA Schema
And may want to see what nico has to say about the sound it delivers here:- SSA Experience

The circuit has been built and tested by Nico as he reports its his daily-use amp. However, I'm not sure if he built it on exactly this PCB or not. I couldn't see any errors in this PCB, so think you can give it a try. ALL will help.

Hi Shaan,

Hi Naf. Congrats! Yes it is okay. You can use even a 100pF with no problem.

Hi Abetir. You can get the layouts in PDF right here:- Alex's SSA-Nico V1.4

offset -0.2 ~ 5 mV

Your measure is same as mine.!.

The active devices are a mirror copy of the ones I used here! LOL

I rechecked the offset again and it reads 11.5mV.

P.S. peeceebee with servo is almost done.

I found a PCB maker here named Nutech and hopefully will get a bunch of them soon. HOHO

Ooh! RED LEDs look HOT! COOL! Nice job naf!
