I don't think you want to run it in SSB (4kV) mode with a continuous output
(like data or AM). My 3K-A with RF Parts ZGs will do that, too but the Tubes
get pretty bright orange!! I can get almost 2500W PEP out of it with ~175W
drive, but I stick to 80-100W or so.
On AM, I leave it in CW (3kV) and drive it to 375W Carrier. Seems like it'll
make output there aaaallllll daaaayyyyy looooooongggg... And the tubes only
show a little color. (You know how us AM'ers are!! :-) )

The two 3-500zg's I put in my Henry 2K Classic X show little color at 1 KW
on data modes, modest color, dull red to low orange at 1.5KW mode.
The former is with 3 Kv on anode and the later is with 4 Kv on the anode and
approximately .800 current on the plate. Of course this amplifier had a
squirrel cage blower with plenmty of air going through.
