If its not been opened up, then it has the 15 meter low pass filter on
the input board just like the schematic shows. I still think the problem
is with that filter or its connections to make a tuned circuit at 40
meters. Check that sub board's grounds.

Good afternoon everyone who has been feeding me solid possible fixes. No
solution yet. This AM I decided to focus on the inside of the AMP instead
of outside fixes. So it is on the bench, opened up, dusted and vacuumed out
and, having checked the wafer switch contacts am about to do a careful
"de-oxing" of the contacts to be sure that contact is being made on both
sides. The components all seem sound and not heat stained. There is
continuity to the Shunt Board and to the coils.
(I'm also going to open up the 10 meter position - but I have to write to TT
for those instructions. After all, somebody has to ironize the E-layer or
this new sunspot cycle will never begin!)
I will keep you posted. MY TNX
