Correct in that you don't normally
obtain all of a tube's amp-factor.The 7B4-- as a driver for a 2A3 has
been very difficult to beat. Theoretically,
it's not ideal.The trouble is-- it IS almost ideal in
this app.I get a kick out of the 12BZ7A discussions.
That's just THEORY. In actual use, it's
one of the very few driver stage tubes that
actually works!Run your own tube tests whenever you have
a question about whether published plate
curves are correct. In most cases, they're
not even close to the tubes we actually buy and use.-Dennis-
