Only difference in typical usage as AF amplifier is that metal 6J5 has it's shell connected to pin 1, so you need to make sure pin 1 is to B- or "ground."
In any case, super low readings with a dependable tube tester probably points to unrecoverable defects. They're cheap enough and plentyful, so toss 'em.

Yes, an internal tube short could do that too.
