Hi GilBenn

Capacitor can (67) is a dual 8-8 uF unit. The original was rated 475 volts each section!

I would not use less than 10 uF, 450 WVDC; 500 WVDC would be better as a safety factor. True, the input filter is not likely to see more than 350-400, but I would rather be safe than sorry...power transformers aren't cheap!

The single can was originally 16 uF, 400 WVDC. 22 uF, 450 WVDC would be an ideal replacement.
