Steve,

Thanks for the reply. Too many sites these days, it's easy to miss
something, somewhere. In any case, I was wanting to isolate the driver
stage from the output stage, and since I have 2 220 VAC secondaries on
the power transformers, I was originally thinking to put one bridge
across one of the secondaries, and then another across both in series.
I have since seen a discussion on AA that suggests that this would be
catastrophic (though I don't quite see how). If I had the 400+ B+ for
the driver, I would drop it with a large, hot resistor and maybe a
choke to further isolate that stage. I suspect that simply using one
secondary with a CLCLC for the output at full voltage and a choke
loaded LCLC(maybe one more LC) for the driver would work as well or
better and avoid the higher voltage complications.
