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.
https://www.arraysolutions.com/amplifiers-rf/om-4000a   You can even place the 
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.
