R4a s/n 5404b has erratic, changing audio levels. 6EH5 (V7) gets very
HOT! Pin voltages and resistance readings a little off ( IAW tube chart
in alignment procedure). Can tap tube and change audio and signal
levels. Changed tube with no improvement. Previous posts show very
different voltage and resistance readings from those in my manual. I
have the 11 tube version. Open to suggestions and comments.
I refer to this GREAT site daily, and hope to be a constructive
contributor in the future.
73, Jim, K5EH
