I found this amp on Craigs List - it was sitting in someone's attic for many years. Needed a lot of TLC - most of the paper caps were bad. Bottom line...This is a fantastic amp with incredible gain and decent volume. 2 6V6 power, 5Y3 Rectifier, 2x12ax7 and a 6sq7 driving the tremolo. About 14 watts through an (original) 12" Rola speaker. This thing screams with Humbucker and P90 equipped guitars.....oh yeah and a Tele sounds pretty good too.
