IIRC a  6L6 is a vacuum tube with a 6v heater.

But (a)  Why were you trying to get it to oscillate?  Isn't it an amplifier?
(although the difference between the two -- when intentional -- is usually
just the type/degree of feedback)
     (b)  Why weren't you trying to use a germanium transistor?  They were
as exciting to get to run over a MegaCycle/sec (yeah, I remember that's what
we called it back then) as were tubes.
