The 50L6 is NOT a relative of the 6L6. It is a pentode
power tube with 10 watts of plate dissipation compared to 19
watts for a 6L6. The 6L6 puts out about 2.5 times the power
when operating as a single tube Class-1A aplifier. Other
characteristics are also different.


Yeesh! That is not good at all! That is a very misleading number in
that case.

What about the 25L6 then? I have pitched a lot of 25L6 tubes
over the years because they showed low transconductance compared with a 6L6.

Personal opinion of mine...I think the * manufacturers* intended a
35/50L6 to be a DESIGN replacement for the old 6L6 as applied to AA5
50s-60s radios. Walks the same walk but its a 150 volt tube.

No question about it....its not very closely related if you're looking
from a conventional 6L6 perspective. 25L6 is sort of a different animal
not related to either of the two.
