Hello NU0C,
Re Message 10, Drakelist Digest, Vol. 34, Issue 4.
Thanks very much for listing that reply regarding Sharp and Remote Cutoff in
the use of Pentode Tubes.
That elegant explanation clearly showed how each tube worked, and I am now that
much wiser!!
I had looked at Lurch's graph and thought that the 12BA6 does not cut off but,
it never occurred to me that 'transconductance' was probably the reason for its
selection.
