|Fender Twin reissue - Channel switching thing|
I've been working out a few kinks on this '92 Twin. All that's left (hopefully) is some incomplete channel switching. It won't mute the clean and the LEDs sort of show what happening -or not. Either the Clean (full-bright) and Dirty (right) LED is dim or both are fully lit. I cleaned the input jacks and reflowed all PCB points. Using Fender footswitch nets same behavior. Any ideas or things to check for?
Mods that work well on the dirty channel are" Marshalize the tone stack, kick bypass caps down to 1uF, C24 to .0047, 680pF across last plate cap, added some shielded wire to some grids. Still not perfect but MUCH better.
