I have 3 Mullard 12au7's that test good in my Heathkit TC-1 tester, no shorts. The 2 with clear logos measure very close on the tester.
I have a boxful of tubes so I can get rid of some of my tube stock, 12at7's under test tonight
codes are:
Gf2 B5C3
Gf2 B5E1
Gf2 B5smudge smudge
all from 1022-538 serial
Halo getters and ribbed plate
The code suggest they're from the Blackburn plant and depending on who you believe either 1963 or 1974, I'm still working on reading all the codes.
I'll work on pictures of the tubes under test. For now.
