No schematic seemingly available, anyone know if circuit similar to anything else? Owner no longer remembers what the problem was. Protect LED goes from red to green and blue power LED comes on. Cold testing the top layer of bipolar output devices seems ok. Says "professional" on the front but 1/3W resistors thrown in "6 transistor" radio fashion. One base resistor lead is broken, presumably from vibrational resonance fracture of the thin 1/3W wire, but that would not be the problem
