Guys and gals, I just read in another group how one of its member got thrown across the room and nearly killed simply by touching a damaged resistor in an amp he was working on.
Peter, as always you provide some good insight. I have several old
vacuum tube AM radios that have electrically hot chassis, among them a Hallicrafters S-38E (the metal cabinet is insulated from the inner hot
chassis) and a 4-tube Sears Silvertone (model 2 chassis 132.878).
What's interesting about the Sears radio is that it doesn't have the
usual internal loop antenna - instead there's a length of wire that
needs to be extended and that wire, while cloth covered, is hot wrt AC
ground. Both of these radios have a non-polarized plug attached, and
whether the chassis is hot or not depends on which way the plug is
inserted into the wall receptacle.
What do you think about replacing the old plug/cords with a polarized
plug end so that the chassis remains "cool" (either in direct or
indirect contact with the AC outlet's neutral rather than hot wire)?
Thanks for your time and comment. Sincerely,
--
