Hi Pat
Okay, now that we're clear on what's going on...
Remember, a capacitor blocks DC but passes AC current. Nearly all Philco chassis are slightly "hot" due to the AC line bypasses used in them. And why you will see a slight spark when you connect a ground wire to the GND terminal. Terribly simplified, yes, but I apologize as I don't really have time to elaborate - I'm sure Chuck or someone will jump and and elaborate further. Anyway, this is why I use new X-Y units at .008 uF instead of .015. Most of us today have agreed that for safety's sake, you really shouldn't use anything larger than .01 uF as an AC line bypass due to the leakage current increasing with larger values of capacitance.
If you were to test further you would find that the voltage may be 73 VAC but the current would be very minimal. Remember, it is current that kills!
