well i have a pair of 4-1000s there really is not that much involved i did not
run mine of am i have seen amps ran that way. my pair of 4-1000 probably weighs
in around 300lb but i dont have a modulation transformer or a choke in mine.
mine will run on a circuit of 30a i have never seen the lights dim with it but
i have 5 huge capacitors on the bottom with the plate transformer. it runs
about 6500v on the plates. i use a piece of copper pipe tied to a broom stick
handle to drain the caps when i want to work on it.
whatever output i ran i always got fine reports. primarely on 75 mtrs as on
the other bands its just too much. it is an entertaining amp let me say that
and it is so fun to watch those plates on the 4-1000 get cherry red but never
burn up.

Oh, yeah!
I’ve heard those guys.
I remember one guy telling the group that his plate
modulation transformer had to be lowered into the basement
with a fork lift. They needed to cut a hole in the floor for
the it to fit.
He sounded like WDBM.
He ran a pair of 4-1000s, modulated by a quad set of 813.
The guy was a retired radio engineer from a radio station.
most of the audio stuff he got when the station he worked
for retired it.
I bet when it fired it all the way up, you cold see it
leave!

A man with one clock knows what time it is. A man with two
clocks is never sure.
