About AP 1.7 with two supply boards - this means new production documentation and higher price. Probably it will be cheaper to buy 2 sets of AP1.7 in present version
No problems on my part.
Hi!
If we get Nelson Pass Agreement, I update my order :
2 * P1.7 PCB
2 * PSU PCB
if not possible, i want as many 'sets' as necessary to get 2 PSU and I would prefer gold.
Perhaps It could be more acceptable by N. Pass if we just order PCBs (and no documentation...there is enough in Diyaudio.com).
In my humble opinion, this is DIY, so searching and understanding is part of the pleasure as much as building and listening.

Waiting for MR Pass permission I made some modifications on AP PCB's. I also decided to separate AP1.7 from supply board so dual mono is available now

An externally hosted image should be here but it was not working when we last tested it.
Great news, VeteranI also decided to separate AP1.7 from supply board so dual mono is available now
The boards look very nice

Taking a brief look at the pcb artwork, I got a little confused:
IRF610/9610's pinout is "GDS" (correct me if I am wrong), but here the gate resistors seem to be connected to the center pin.
Someone seems to have mixed up gate and drain - is it me or the board's designer...?

Everything is OK with the layout - my version of AP was tested by several people I draw transistors footprints above to show mounting holes and dimensions. Take a look at PCB from bottom:

So yor actual layout isn't identical with the one posted on the first page of the thread?veteran said:Everything is OK with the layout
I attached a screenshot of that (early?) version, and that definintely has errors. R33, R13, R22 don't connect the FET's gate pins, as they should, following your schematic.
