Hi again,

Just wanted to let you know I found the cause of the low plate
voltage on that 7C6. It was a very leaky coupling cap #67 (.01)
going to the output/s. Replacing it brought about 167volts to the
plate and there is very good volume plus much more reception
across the broadcast band.

Just tried the shortwave band and have absolutely nothing coming
in there though. I just have a length of wire clipped in for my
antenna on one of the screws as it is hard to hookup the built
in large loop just while working on the bench. Could this temp
antenna method be the reason for the no SW band?

Thanks again!
