[Amps] How Do You Know When Filter Caps Begin to Fail?

[Glen Zook]

The electrolytic capacitors in my Henry / Tempo 2001 lasted for 38-years and then 3 of them "went" at the same time.

Hi Pete,

When the filter caps in my filter string started to expire, one by one, the fuse in the 2.5 KV power supply would simply blow...

I finally grew tired of replacing them one by one, & simply wholesale replaced all of them. Surprisingly, the caps lasted some 32 years---but electrolytics seem to be like lightbulbs in that they all "age" at surprisingly the same rate. I guess once you lose one, "...it's time"!
