I think CS leads to Wilcox.  Air Asssociates made T-4's
maybe.

The manual man had some T-4 manuals before he closed,
if he really closed.  I installed a few T-4's, and maintained
a few.  813's ought to work if you bias them properly.  The circuit
is simple enough.  PA had 1600 volts, and 400 MA was
max PA current.  That was about 400 Watts into antenna.
Someone will come along and tell you how to compute the
impedances of the modulation transformer, I'll bet.
