Quote:Don't use electrolytic's in the filter can, use 630 volt poly caps.

I have read this many times but, I don't understand why. When I look at the 20 schematic, I see the power supply is virtually identical to the one used in a 70 or a 90 or just about any of the other Philco models. So why are electrolytic capacitors OK in a 70 or a 90 but not in a 20?
