Hi all,
I am using the Henry 2500 PGC/27 as an amplifier on 10m without modification.
Mechanically (socket,chimney etc) and electrically it is the same as the
3000D.
Original frequency is 27,12Mc, unit consists also of 6146 predriver and
4-400A driver.
Tuning is done by a damped coil with very good efficiency up to 30Mc, the
whole circuit is Pi-L.
