PT96 - low plate voltage
#10

Was also thinking if you are the adventurist type and you had a small audio amp you could see if the rest of the set is working. The amp could be something like the amplified speakers for your computer. Two important things 1# You must use an isolation transformer or make sure that the chaiss doesn't have 120VAC between it and earth ground. If you don't have an isolation transformer you can connect your volt meter to the chaiss and earth ground with it set on AC volts plug the set in. With it plugged in one way it will show 120AC turn the plug around and plug it back in and it will read 0V AC. You want it to read 0 VOLTS. If you try it the other way you can get a helluva shock and cause other thing hooked to to burn up. Don't ask me how I know! #2 Must use a cap to couple the audio signal from the set to the amp. Size isn't vary important anything from 500mmfd to .1mfd is OK 200v or better. Solder it to pin 2 of the 7C6 other end goes to amp input. Double check voltage from amp chaiss to radio chaiss . Should be 0 VAC. Hookup just the filament pins on the 50L6 like before.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
