Nice, but a tiny bit more than I'd want to pay.
When did the FCC permit 4 KW amps for the amateur service?
I use a single FU728F. 2 should be capable of 5000 PEP out. Keep going
and it'll be better than solar panels. <:-)
They are calling drive power, the input power. IOW, with a 100W in they
are getting 4 KW out. The input power at an optimistic 60% efficiency
would be 6666.67 Watts. Keep going and it'll be better than solar panels.

Comes with a pair of 3 kva CCS torroid plate xfmrs. Also has FCC approval.
Compact, sits on any table,
a meager 101 lbs. Heck, it even uses a pair of chinese FU-728F tubes..which
are cheap to replace, $475.00 each.

amp into another room, and
operate it remotely, with the mating remote control box, made for the automatic
tune amp. https://www.arraysolutions.com/om-4000-rem
Your heat issues and noise issues have now vanished. Use the supplied cable,
or use the internet. No PC required at remote end.
## Ok, if you want the manual tune version, its then
https://www.arraysolutions.com/amplifiers-rf/om-4000hf
Both versions can be driven with just 70-100w. Has 16 db gain. 160-10m,
including all 3 warc bands.
## Matched pair of tubes, cheap.

## Both the manual and auto tune versions appear to be a big bang for the
buck. Then you get to do
cool stuff, like boil oil....and test baluns.
