Tubes Asylum

Questions about tubes and gear that glows. FAQ

So... I downloaded some of the tube ID sheets and really gave a good look around, but out of a batch of 10 or so, 3 of them just don't want to give up the ghost....
The first appears to be a twin triode 12A.. series, but need to verify with the asylum knowledge base. Good looking tube whatever it is...
The other two might be easier...
I THINK they are an EL84 and a 7189 from Mullard, but I can't tell which is which.
One has a date code of km1/BOB3 and the other has what looks like
?X3/B4J3 Can anyone confirm my suspicions on these.
Thanks for any and all help!!
