My 1968 Bandmaster has been recently recapped and restored, It was running fantastic for about 6 months. Last night I turned it on and it only had about half of its power. I tried the old tube swap thing with some extras that I had, but no change. The strange thing is that I have a Ibenez tube amp pedal that brings out the volume to normal along with the tube screamer distortion.I plugged straight into the amp thinking that it may be the cables or the pedal, but still only half power
What should I look for as the possible cause of this
