Default Re: AVO VCM163 - Some faults I have had

Of course, another way of doing the heater continuity test would be to treat each 6.3v filament individually. Pins 4 and 5 would be treated as "no connection" in turn. I am not too sure whether the two filament pins are actually physically close to the pins of their respective triodes, but a lack of continuity in one would be obvious; then which triode it applied to would also become plain when Ia and Gm figures were taken.
