Arran,
The final answer to your post about the two bad 6J5s where you wondered if my tester is OK itself: today I received from the eBay 10 used "test good" 6J5GTs (could not resist 10 pcs for 19 bucks whereas the rest sells them for 10-12 bucks a piece) and tested them all; the "new" value is supposed to be 2600. All but one tubes test at least 2,200 and several 2,500 - 2,700. Only one happened to be 1,800 (between good and bad). At the end I put the original two in - you guessed it - same as they were, 100-150, that is dead. So, yes, it is the coincidence (whatever the reason is) and not the tester.
Mike.
