I'll take a stab at it. Need to know the dc voltages at pin 3 of 6V6, pin 4 of the 6V6, pin 5 of the 6V6 pin3 of 6Q7 And the grid cap of the 6Q7. Both pin 5 of the 6V6 and GC of the 6Q7 should have - voltage on them. All voltages are measured with - lead to the chassis.

Thanks, Terry, for the assistance.
I measured the voltages of the tubes and here is what I got (if I did it correctly):
6A8 - #3 is 293, #4 is 86, #5 is 13, #6 is 293
6K7 - #3 is 290, #4 is 90
6Q7 - #3 is 84, #5 is 0, grid cap is 0
6F6 - #3 is 290, #4 is 292, #5 is -128
This radio doesn't have a 6V6.
Hope this gives some clues and thanks again.
Dave
