On my 16a there is a dual segmented .05uf capacity on each of the main power wires to ground. It’s good. But it’s 75 years old. Any issues removing it and putting on a grounded polarized power cord?

"Thank you Norman! That’s great news! I have no reason to believe it’s bad other than my meter. I’m testing and replacing all the small caps and resistors (most of the resistors are 15-20% out of spec). Figured I would check this…"

"That is a paper in oil capacitor with higher leakage current than wax-paper capacitors being normal.  This will cause some capacitance meters to read high.  It is most likely good.  If voltages are as expected and the capacitor does…"

Capacitor replacement

I am having a hard time sourcing a replacement for one of the capacitors in my 16A. Any help would be appreciated. it’s a 4uf 600v can type with a screw base to mount it. I can leave it in the chassis for aesthetics and replace it with a different capacitor underneath, but all I have found in the same spec is a polypropylene film capacitor. Can I use that?  any other ideas would be great. This one is measuring 8.4uf. It’s bad. …See More

"https://www.justradios.com/cart.html  among others sells the safety caps.  I never thought about the inrush of these tripping a GFCI.  I don't run any radios or test equipment on a GFCI, so I usually stick with what was original…"

"I did pull one of them, the first one wasn’t so bad. Both resistors under it were 20% out of spec, both caps were Mica.  other Mica caps in this set were out of spec but haven’t pulled these to check them. "

"I have seen these old mains capacitors blow in to a million pieces- paper confetti everywhere.  The capacitor(s) are there for EMI/RFI filtering, so regardless of having a grounded cord, you should have capacitor there.  Use a proper rated…"
