Terry,
I replaced the power cord before I applied power. With the switch on I measure 9.1 ohms on the power cord, 242 ohms between pins 8 and 10 for the 80 plate, 144 ohms between one of those and the center wire no. 9 and 349 ohms between the other one to pin 9. The filament wires 6 and 7 measure .8 ohms. I did notice that some of the pt wires were brittle, and I put heat shrink sleeving on them. Would pulling the pt and replacing wires I can be worth the effort or is the pt shorting out?
I appreciate your response and the help you have given me.
George
