Thanks for the kudos, John!
Could you or done describe the protective bias circuit you refer to?
Probably could figure it out, but the group may be interested as well...

CONGRADULATIONS A JOB WELL DONE!
I really like the choice of tubes. I don't know what a T55 is but
probably one of the special Taylor triodes with 55 watts plate dissipation.
Probably not a lot different than the 812s but I know that the 812s are very
good tubes to use in a class C plate modulated rig especially if used with
100% grid leak bias or the configuration that Don, K4KYV, uses where there
is a safety bias supplied thru a diode and the diode becomes reversed biased
when RF drive causes grid leak bias. The 100% Grid leak bias DOES make a
difference in the modulation characteristics of the rig.
