I have double and triple checked, and C12 is installed correctly.

It is a brandy new cap from the WB kits sold here, and I have even
replaced it with the cap from my 2nd kit with no change.  I guess I
will try the suggestion of a tantalum cap(s) and perhaps even changing
the values in that area (cap first, resistor R38 second) to get the 7.8+
volts at pin 5 on U3...

Thanks everyone for help!!!
