I HAVE A VERY OLD 1930S-40S PR MALLORY & CO. CAPACITOR. ITS VERY LARGE SQUARE CAN TYPE. I HAVE ON THIS CAP 20.0 MFD AND 330 VAC. ITS NUMBER ON IT HAS A2050.34-1. IT HAS GE PRINTED AT THE BOTTOM. ITS FOR AN OLD 1/ 2 HP BENCH GRINDER. RATED AT 5.2 AMPS. I KNOW BY TODAYS STANDARDS IT IS LARGE. 3 X 5 X 5 INCHES. IT EVEN LOOKS MILITARY IN GREEN. IS THERE A BETTER REPLACEMENT CURRENTLY AVAILABLE. IT HASNT FAILED BUT PREVENTATIVE GOES A LONG WAY. THANK YOU FOR YOUR HELP. KENNY
Hello Kenny,
Are you able to provide a picture of the capacitor? Mallory capacitors is not Cornell Dubilier so I would imagine there is going to be a completely different system for part ordering numbers. With the specifications you’ve provided, along with any information you can provide as to how it is terminated, we may be able to find a replacement that works for your application.
Please see this link for capacitors in stock having similar ratings. Due to advances in technology over the last ~80 years none will be a direct fit, though any would appear to be a reasonable option electrically based on the information given.
