I recently noticed a drop in volume and clarity in channel one. It isn't noisy, just not as clear. In the 90 watt mode, I could have all my channel masters set the same and the volume would be balanced across all the channels. Now I have to crank ch one quiet a lot to balance them. I'm guessing a tube but not sure if it is pre-amp or a power tube. Did the tap test but didn't hear any noise. Any suggestions?
A side note, I have a 1962 Fender Pro amp that my father bought new. It has never had anything replaced including the tubes! Still has the 2-prong power cord. Makes me wonder why the newer amps seem to go through tubes so much faster.
