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.

He’s also a guitar guy that enjoys building and rebuilding amps. He has a few signature pieces such as his Pure Daddy Combo, a skillfully reconfigured EVJ chassis and cabinet with a hand wired point to point Champ circuit. He also is extremely skilled at rebuilding vintage PA amps like this one, voiced for guitar and/or harp. Carl will also take special orders to modify or repair your amp or revoice it for your individual needs. If any of the amps we modify come to us with death caps, they are replaced with a safer circuit and all amps are outfitted with safer 3-prong electrical plugs. The new badge and labels placed on the amps are there for your convenience but are readily changed or removed at your discretion. We have other vintage amps we are working on but this is the only one of these we have. It’s unlikely we’ll find another, especially in this condition.
