Even the mighty

Curious Marc (and crew) mess up at times:

origin of the smoke: see the little orange dots just visible on the slip ring

The magic smoke wasn't really their fault but Ken trying to explain it away ?  NG :)  Also forgetting the magic phase shift cap a couple times ?

Take aways:  even though it's completely different, use polarity protection (your fave method) ALL the time - yes I hate the smoke !  Also, if available, use current limiting to let you know when there are shorts by having the supply voltage wilt.

Also:  isn't it interesting that with a room jammed with HP meters of all kinds and generations they use a Tek meter to find the short ?:

Curious Marc also likes to use HP scopes in favor of Tek :)
