.001uF cap to the on/off Reverb Pot was bad...replaced it and I'm in chiming shimmery Gretschy/Valco heaven
Thank you all for putting up with my lack of knowledge and helping me fix my first amp ever!
She is mostly original, but a previous owner changed the baffle board to a 3x10 instead of a 2x12. So I have 2 SICA SLD 10/80s in parallel on the reverb side, and a single vintage Jensen p10R on the normal channel.
