[TenTec] Corsair Troubleshooting

[Stuart Rohre]

Hey Dan!  Good call!
Guys and gals, Dan has hit upon a common hum causing failure that I had
forgotten to mention!

Yes, one diode out in a bridge, (common rectifier in todays linear or
switchers) and you have a hum generator!  Been there done that!
