If you plan on collecting more sets you really should get a variac or make a dimbulb tester to soft power your sets.

Thanks for the heads up. I'll try to gently pull off the broken knobs later, hopefully they won't put up too much of a fight. Patience is key...

As for needing a variac/dim bulb tester, I am well aware. I'll get around to it somepoint, this is one of the few exceptions in which I powered on the TV before going through the caps/resistors/etc.
