Terry,

I restored a Magnavox 1947 radio/record player console and while re-capping left these alone as I thought they were mica and were more or less bulletproof. They were exactly the same type caps as you pictured above. A while after returning this radio to almost daily use (I really like it) there was a smoke episode. One of thes caps literally split open letting the smoke out. It was one of a pair, each connected from opposite sides of the AC line to the chassis.

PS: Come to think about it, both of 'em shorted and split from the fault current. Where they were, one going short would have caused a hot chassis but not smoke.
