Are you sure? Won't shorting the 10n switch between 22.01uF and 22uF... Not between 0.01uF and 22uF?

I'm suggesting you only need the switch, Shorting the 10n will have the same effect as adding the 22uF.

Ohhh, I understand. You're saying don't even add the 22uF. Just bypass the 0.01uF for the same effect. I'll give it a try with a temporary wire and see how it sounds. I could also try a few different cap values smaller than 22uF haha. I'm just going with 22uF because that's what the manufacturer said they're using.

Glad this amp is getting on its feet!

I'd also be interested in seeing the schematic. I have a Hiwatt clone that I can't leave alone, so I'd be curious what they're doing with it.
