Thanks for the link, I didn't think to search on 'wiring' for some reason.
Joe, Okay, I see, the buzzing is a feel, not a sound. The audible buzzing I was talking about was from decades ago. When I was a kid I think one of our lamps buzzed or maybe it was our cabinet stereo. It's funny what triggers memories - that's not something I would have thought of if you hadn't mentioned buzzing.
