To start off i am not a tech head. I have an early 70's Fender Vibrolux Reverb that just got brand new tubes, caps, pilot light and a new power cable. I can't turn the beast past 3 1/2 without a hell of a buzz. Its humming through all 4 jacks, (normal 1,2 and vibrato 1,2) alot louder when the treble is up both on the amp and the guitar. The buzz is quieter when not on the bright channels. Any advice to quiet this thing will save my life. The tone is perfect but i can't turn up the amp, i need those natural hits. Please, again not a tech head.
