That is the first I heard that WB8TNY was a secret Ken.....been common
knowledge for years. Denny used to tell anyone that...even at Dayton.
The LK-800TNY can do 5KW PEP out on SSB since it uses a xfmr with taps.
Amp Supply supposedly got Eimac approval for 3KV on the 3CX800A7's in SSB
service...I never saw the proof. On CW you are "supposed to" switch back
to the 2200V tap (panel switch) but I wonder how many do ...and what is
the tube life in that amp?
A stock LK 800 will do close to 3KW out at 120W drive and still not
exceed the ratings of the original Eimac spec sheet.
If you want to push the tubes as hard as Ten-Tec, Command, etc (100W a
pair...way over specs) even another few tenths of a dB is possible with
150W of drive.
IMO...only Eimac wins in those situations.
