The 50A1, by contrast, is a thermally-variable resistor and contains nothing radioactive.
OK that makes sense. Sorry about the confusion, I didn't relize that it could of came from that. Anyways now that's cleared up maybe we should get this thread back on topic again. So anyways I've been having some issues with a scratchy volume control and was wondering how I might go about clearing that up?
