Thanks! Two pairs is good for 70+70VCC?

Not really, especially if you drive less than 8 Ohms speakers.😱

Here is the mirror image
I modified after my taste, I left out the fuses on the PC boards. Also I made it iron transfer friendly. Based on my experience, when you print it out please open it with Paint and set up your printer to match the PCB size.

I think that would be pushing it too hard. The layout is for three, why not just use three pairs?

Yes, I want to do with 3 pairs. The PCB on post #11180 is with 2 pairs...

No, A40 is a CFA amp and SR200 is VFA.

I used Alex's layout in my A40 also.

I would suggest you to build the AX-14 , many happy people have built it and its well documented (through out this vast thread😀).

recently mprivitera has PCBs, so will make you build very easy, if he has spare and can sell a set to you.
.
I may also have PCBs for Apex AX-11 Bimo mod, that simulates well and one of the members who had built it long ago was very happy with it.

P.S. I would also suggest you to look at APEX FX-8 or FX-8 Bimo Mod that many people considered very good. I have built APEX FX-8 and personally I liked it very much. I plan to build APEX FX-8 Bimo Mod version too.

Thanks for the answer

What's CFA and what's VFA for?


Also, did anyone build both SR150 and A40? How do they compare?
