Well, the patient has survived and is playing pretty well. For now I am using an AA battery in place of the bias cell, I will get an LR44 installed tomorrow.

One concern though, the chassis in the area of the Candohm resistor is getting very hot, though I do not have the means to measure the temperature.
Voltage across the resistor is 45V, and if calculations are correct it is consuming about 13 Watts. Overall the radio is supplied with 112VAC and is drawing 390 milliamps.

No asbestos in the cabinet in this area, would there have been?

Thanks,

Russ
