Mr. Fixr, The schematic doesn't show a "jumper", but on Section 2 of the schematic, it is where C201, C204, C206, the black wire from Z301, R201, and R206 all connect to Pin 1 of the 1U5. There is a 6-lug terminal strip where lugs 3 & 4 should come together. One lug alone woud make a very sloppy connection indeed. I now recall cleaning both lugs and reattaching them in a cleaner fashion. I forgot about the jumper. I'm puzzled about the low A+. When calculating for the resistor drop of the 1N5408, I used:
R=drop/IDC = 10V /0.063A = 159 ohms.
The closest I could come up with was 135 ohms at 2W.
I will ponder this and maybe look for 150-160 ohms at 2W, but for now the unit plays nicely.
Thanks to all, Joe

Courage will follow when Faith takes the lead.
