hi all, rich wrote... it is perhaps important to note that an increase in the resistance of a composition resistor (or a film resistor, too) can increase when the resistor gets too hot. (rich has sai

Hello all, Wonder if anyone has ever acurately measured a reistor for a parasetic supressor before assembly, soldered it to the PS inductor, then un-soldered and re-measured the value? I would be int

George and others: I have brought this point up many times here...I'll try AGAIN. A 2W carbon resistor will show a gradual and steady R increase when run above 1W or so....this is at DC. At RF, the h

Amen Carl. That's why carbon resistors should NEVER be used in power supplies across electrolytics. Once again VERY true. That is a natural characteristic of the resistor. You have to NEVER run the

Years ago I worked on a GE High band VHF base station that had blown the AC fuse in the plate supply. It was an old unit, in service about 15 years. The trouble turned out to be a 100K ohm 2 watt ca
