Ok Paul, this is helpful.  Let me see what I can find.  I'll report back.

Thanks for guiding me and wading through all the measurements.

Yes, double check those center lug AC signal voltages to verify the bottom lug is zero.

Doc and PB:  It's fixed and it sounds great!  Listening to Brian Auger's Oblivion Express album Straight Ahead.  Wow!  See picture.

I re-flowed the solder on the volume pot connections.  Also, you know that balance pot lug that is tricky due to having 3 heavy black wires in that tiny pot lug?  I re-made that connection which was kind of wonky.  When I measured the voltage on the right channel lug of the volume pot......there it was: a signal!

This would have taken me forever without your help Paul.  I apologize if it was torture.

This is significant because I built this one for my friend Tony.  Now I get to build one for me.

Thanks again,

John

Impossible readings are indeed often nothing more than a missing ground connection. I'm glad you found it.
