Of course, all this was overkill running it at 1KW on the ham bands, even
100% duty cycle on 20M RTTY for hours on end. I'm not a real math wiz
when it comes to calculating plate power, especially in the heat of
workin' some rare DX on a Pacific island that only is out of the water at
low tide, hmm.....950ma, 6200VDC....lessee....yeah, that's pretty close
to a kilowatt in, right?....(c; Hearing the 5KVA power transformer that
ran THREE houses buzzing away when it was on the air, I called the stupid
rural electric coop to warn them before it exploded. They poo-pooed my
request for more amps, but became believers when I blew the bottom out of
the transformer, setting an oil fire that burned up the whole pole to the
ground! A new pole and 15KVA beast seemed to cure the problem. I told
them my neighbor had a new hot water heater...(c;

Yes, but isn't increasing the input power from 1KW to 6KW, disregarding
inefficiencies, only about 8dB signal increase?
