Hi Eddy,
It's the identical tube with the supressor grid internally connected.
I've used them in several Drake Xmtrs with fine results. Others have
reported difficulty with neutralization...but I've never seen that. The
specs as I recall, were not close, they were identical.

Hi Mike,
From a thread re. Drake finals here of some two years ago, there was
mention of the fact that the 6GJ5 is a direct substitute for the 6JB6, if
you have no luck finding that latter tube...

Subject: [Drakelist] 6JB6 vs.6JB6A
Thanks for the info on 6jb6 vs. 6JB6A. I have seen a few 6JB6 of both
varieties on line, often advertised as MATCHED. I wonder how they have
matched them as some have listed an emmisson only tube tester as the match
unit. I am very leary of these so called matched tubes! Even the ones from
the large tube sellers may be useless! I was given a T4-R4 set which I
took to WB4HFN. He went over them and said that I would need a new set of
finals after I had used them for awhile. I am having some trouble getting
a wire up for them, but I keeping my eyes open for a nice set of 6JB6 s.
