No, I have not performed a formal test, but some simple bench tests show something like 50 WPC. I just do not have the distortion figures at those levels.

Thanks Loren, not so interested in the distortion level just rough output power, the distortion IMHO is secondary to how the amp really sounds

Or drawings?

I was not planning on selling boards, but I can have them made if you have an interest.

prices get kind of expensive when doing low quantities.

I would not be looking to make a profit, just pay my costs.

Could you define "kind of expensive"
and "small quantities" please.
I would think there would be others interested.

Let me see what the cost of each board is for various quantities and I will report back.

It all depends on how many boards are ordered and how many people want these boards.

There are three boards to the set (Power supply, HV Delay Board, Driver Board), but you need two of the power supply boards to make one stereo amp since the amp uses a power transformer for each channel.

The Driver Board contains both channels, but you can always cut it in half if you want to make two separate mono blocks. However, you would need an extra Delay Board.
