Zenith 25EC58 Restoration Thread

Ripple current rating of a cap usually isn't tied so much to B+ ripple voltage as it is to series current. Without seeing the schematic I can hazard a guess that the cap with that rating is either the resonant cap in the transformer or it's a series AC pass cap in a B+ doubler circuit. Ripple current in a cap usually means that that caps primary duty is not so much to filter DC as it is to pass large amounts of AC power along to somewhere else. Some B+ doubler circuits the main B+ cap does double duty and is there to handle large AC current and filter DC.
