Guys,
I was talking to a guy today on the radio and he was telling me
that he got a sb-220, with a 3rd 3-500Z tube, and it was "all done up"
on the inside. exteral power supply and that the amp is going 4KW PEP.
Is this really possible? or no?
In my experiences, at 3000Vdc, a Mu=130 3-500Z will produce a linear
output of about 800w pep -- provided it has c. 70w of drive. With a Mu
of 200 (Amperex 3-500), a bit less drive is required but the pep out is
the same.
just wondering... I seriously have my doubts.
There is nothing about telling the truth in Part 97. As a well known
amateur in North Hollywood (WA6MFJ) says "you don't have to tell the
truth on amateur radio".
cheers, Chuck
