Wally, Weber also suggests swapping the output transformer with one from a BF Bassman. Have you, or anyone, tried it?
Here’s before and after grille cleaning shots. Some like the funky look, not me I like the "after" look. That’s up to you.
I used a vacuum to get the loose stuff first. Amazing how much crap gets in the backside of a baffle! Sprayed some 409, simple green should be ok, brushed it and rinsed it with a hose. I didn’t go crazy with the hose just enough to fully rinse it. Then let it dry in the sun.
With only a few exceptions Amps are what I regret selling. This is one in the regret file! Recently I found out a tech pal used to own one of Gatton's VR and had recorded all the circuit mods!
FWIW, this amp had no Tube Chart and no evidence it ever had one. 64 parts, Jan 65 Oxfords.
