This is a mid 60′s vintage Harmony Tube amp. Cosmetically everything looks okay, but the amp does not work. When it is powered on, the amp just buzzes, but does not register anything plugged into the line inputs. Looks like the power cable was replaced at some point. Please see the schematics and photos of the capacitors/resistors inside.

Vintage 1965 Harmony H303B “Widowmaker” amp in good working condition. Amp has been fully serviced with Nichicon capacitors, 3 prong power cable wired in correct polarity no shocks! , and a replacement Jensen speaker from 1999. Still has a full compliment of vintage tubes. This amp still has the original grill cloth and rear back panel and is in good shape. Shows some typical wear including snags and discoloration in the grill cloth, wear to the original tolex, and wear to the original leather handle, but overall well taken care of. Was used with a vintage Aloha pedal steel and wasn’t beat on or abused. No smoke or pet odors. Shows normal signs of use and wear for an amp of its age, but overall a really cool little amplifier that works great and has had the right work done to it to keep it running for the next few decades and to prevent any nasty shocks that earned it the Widowmaker namesake. Note: this is a vintage item. I can’t describe every single little nick and scratch, so please be realistic about what you’re purchasing, study the photos and description, and of course feel free to reach out.
