Hi Benni, I plugged your values into a spreadsheet I cooked up ages
ago - came up with 1250 ohms for Plate Load
3000V @ 1.5A, "K" value for AB = 1.65,
Plate load = Plate E / (Plate I * K)

Hi all
I brushing off a old project that I have been collecting parts for quite some
time.
Was going to build a big SSPA, but I just can't throw this old project away,
have all the parts and I always wanted to build a tube amp for HF, built few
for vhf-uhf.
I'm now building the tank, and I have some questions about the Rl value
What value can I expect for these two tubes operating @3000v, max current is
about 1.5A class AB - the normal calculation is giving quite low value
is about 1200 Ohms - Does anyone here have some real world experience what to
expect or what values I should use when measuring the tank?
