I'll check that out tomorrow and report back.  Whatever did go wrong, it did have B+ voltage from it to ground (but zero from the other 6L6 to ground). I always wondered how they got metal cases to seal good enough, I didn't know they were glass inside!  Now you have me thinking, if the keyed pin in the center was off, and the tube was turned a few notches, that would make sense for it to have B+ on the case.

Definitely inspect the socket. Pin 1 should be either left floating or preferably tied to ground. If it's used as a tie point there's no problem with glass 6L6s but it will be connected to the case if a metal tube is used.
