I'm on my third attempt at the Return of Zen amplifier, I think I found a flaw in my original circuit board.
However, the picture doesn't make it clear. If you look at the schematic, it says one of two things:
Connect R11 from -out to ground.
Connect R11 from -out to the input capacitors.
The latter makes more sense, and is the way I did it last time. However, since I failed on my first attempt, I'm doubting everything this time.
I sent an e-mail to Nelson Pass. So, if he responds, I'll have a difinitive answer. So, first, what do you people think the answer will be? I would really like to etch the board today.
Thanks,

Ok, thanks.
I etched a new board with a place for a jumper. So, I'm set. I didn't connect the jumper.
All I have to do now is put the thing together and I'm ready to test it again.
I built a function generator. And I have an oscilloscope. So, I'm going to be able to test it properly this time.
