If you find a hi-fi or 70.7V PA transformer that's great....


What does 70.7v mean?


My question for you: what kind of modulation transformer do you use to
drive the plate for the 8000? I'm jealous that you apparently had one
just sitting around :-).


No such luck but I did find someone else by trolling who did. It's a
UTC SS22 and about right for the job but I would feel more comfortable
with something a little bigger.

I only need about 200W of audio but I would like to run it at 2000 volts
to get legal limit out of the final but I am a little reluctant to push
the mod trans. I am currently running at 1600V and everything is happy.
