I am in the last stage of restoring a 1964 General Radio Frequency Standard Model 1120-AB.
I'm having trouble getting the inner oven to work propoerly and the problem has been traced to a defective thermostat in the inner oven. In checking, the thermostat is a thermoswitch manufactured by Princo and is no longer available. My options appear to be: 1. locate a working GR Standard Frequency Oscillator (1113-A) and replace the entire chassis. 2. locate a non-working GR Frequency Oscillator and part it out as needed 3. find a suitable replacement for the original thermoswitch (78 C - closes circuit when temperature is reached) I was wondering if anyone on this list has any sources or leads for #1 and #2 and any opinions on a source for #3. Thanks Russ WA3FRP _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
