Replaced all electrolytic and paper and foil caps with new except for three 20uf caps that are back ordered. New log volume pot, and linear treble, bass and input impedance pots. New power cord and power/tube filament interconnect between the top and bottom sections. I am leaving the two multi-caps in place, but they will be non-functioning....with new caps under the chassis. I also did a general cleaning.
I searched for the problem with the tremolo unit and found that there was a short to ground on the path from the footswitch input jack to pin 5 of the 6SN7 tremolo tube, as I recall. This effectively shut down the tremolo effect. Now it has a beautiful and tremolo effect with both speed and intensity controls.
Now I am waiting for three 20uf caps and I will re-assemble. I show my workbench (see pic) with the top unit inverted to search for the tremolo circuit problem.
Does anyone even care?
I feel like I am broadcasting in the blind.
