This is a cool amp from the 60's.  Made by Valco in Chicago between 1965 and 1967.  Blue control panel, black tolex, silver grill cloth.  Volume, tone, trem speed, reverb controls all function flawlessly.  Tube complement: four 12ax7's, one 6v6, and one 5Y3GT. 12" speaker.  Everything works as it should.  Not a very loud amp, but would make a great recording amp.  Not sure if the speaker is original,  the wiring to the speaker is clearly replacement.
