How long will a polarized cap stand full B+ at reversed polarity?

Only a few seconds at best.

I learned that the hard way some years ago...I had recapped a Philco Model 15X, and accidentally connected one of the main electrolytics backwards. Turned it on and POW!!! Sounded like a gunshot. Immediately unplugged the set and looked underneath. It didn't make a big mess, fortunately, but it was a goner nonetheless. Replaced with another, making sure the polarity was correct...Lesson learned. Icon_smile
