Hey, he knows what a ring modulator is, too!

Just so's you know, I do know my way around a soldering iron... just have no experience with tube amps. All of my gear is solid state. So, I am sure with some guidance I can fix this.

I don't know if he still has my Dad's Peavey Heritage or another amp. Dad used the Heritage with his pedal steel until age just got to him, could not move the amp around without help. Hey, he's 87 and still plays.
