[Amps] 12 KW CCS ON 160-15M....USING THE 3CX-6000A7..... PART 34

[AJ]

Well lets see

~80 amps filament

~3 amps plate current at what 7500 volt ht (depending on line voltage)

~ various ancillary hardware (fans, relays, lights, bleeders, etc)

Don't think a few extra amps of heat is really going to mater. If it did 
an inline inductor would take care of it till the temps change and then 
all bets are off. The other thing is a Sola can fix alot of this but 
more space more hardware.

It's going to take a service to run it anyway.

Any way you look at it there is going to be heat dissipated by the unit 
and the currents voltages are going to change too.

This project is 10 db above what most amateurs have ever seen. Not to 
say there are serious amps out there.

Hats off to his project.
