My buddy has a Gibson Vanguard GA77RVT like the one Scotty Moore used to play. This is a strange one that has an OC2 rectifer, two x 6L6 power tubes, four x 6EU7's and a 12AU7 according to what someone wrote in pencil on the back panel, but sadly there is no schematic.
When we first fired it up, it would only have volume if you turned up the reverb knob, and the more you turned up the louder it got. We gave it a cap job, 3 prong cord, changed the obviously blown out capacitors, and swapped tubes and now it sounds much better, however now you get reverb on the normal channel when you turn up the reverb knob. It is a rich full reverb that is even stronger than on the effect channel with tremolo and reverb, which is very weak, and not quite as loud. The tremolo does not bleed over to the normal channel, just the reverb.
Any suggestions on where to begin, or what could cause this?
