I used a pair of similar 47 uf 500 vac film caps from genelec for B+ supply in my H182 organ. Were rated for motor use. I'm tired of replacing electrolytic caps every 8 years. Were so big I had to mount them in a separate chassis. No problem. Ran a 600 v rated twinax cable to them, + versus return. Its been 11 years since I installed them.
These capacitors are no motorruns, but top notch for filter applications
They could certainly be used for motor runs, but are rated higher current for general purpose filtering. Would be a nice find if you found some surplus, cost a pretty penny at regular price. They’d never need replacement, even in highly stressful use.
