[Boatanchors] HV Electrolytics

[rbethman]

Should one *really* search, they even have 50KV Electrolytics.

Stopping on one result doesn't cover the myriad of said electrolytic 
capacitors.

They either have a lug painted, marked polarity in one fashion or other, 
but certainly are indeed made.

Simply replying on one line for UV lamps doesn't tell the whole story.

Those that insist on being so short sighted, then continue to live in a 
little part of the world that cannot accept that pretty high voltage 
electrolytic capacitors exist.

This isn't to be construed as aluminum film electrolytic types.

There are quite a few other methods to construct electrolytic capacitors.
