A single amp board, consists of two amp channels separated by a scoring line.

For dual mono, or stereo, you will need one amp board (F3 or F4) and 2 PS pcbs for F4 and 1 PS for F3.

Now I will have to edit wiki as I would nead 2PS PCB For F4 ( I was counting that I would nead 1 per (stereo-dual mono) AmpPCB )


@ Peter Daniel - will you send email to every one with billing cost (PCB+shiping+paypal fee) or should we just make payment and drop you email once we make it ?

I'm pretty shure some of the people will use regular bridges so you might be able to find just this part.

I will certainly not send any emails. Payment info will be posted in this thread, as it was done before: http://www.diyaudio.com/forums/showthread.php?postid=1298371#post1298371

Don't do any payments yet, as I'm waiting for price and order confirmation.

Peter,
Maybe I missed it somewhere on this forum, but is it possible to see the outline of the PCB and where the power transistors are? At the moment I am planning the box and heat sinks and this information would help me a lot to organize it all propely.


Thanks.

Ok, I am confused. I intend on building 2 stereo F3 amps and 4 balanced F4 monoblocks. I have ordered one PS board for each of the F3 boards(pairs). I also ordered PS board one PS board for each monoblock F4 board(pair). That means I ordered six PS boards, two F3 amp boards(pair), and four F4 amp boards(pair) to make the amps listed above. Is this correct or do I need two PS boards for each F4 board(pair) to make one balanced monoblock?

So for a balanced F4 it is essentially two F4's. So just to be clear, one or two PS boards for each pair of F4 amp boards? I just want to be certain.

Yes. It is essentially two F4's. I use one power supply for each - using the V+ and V- wired to both boards. Ground is common to all of them. I can send you a picture of it assembled if you like.
