I repaired the Command 2500 of a friend twice.
Both times burned toroids.
Next time I visited him I saw the reason, he drove the amp to 3KW PEP
output.

Maybe, maybe not. I owned a Command HF-2500 (now taken over by Palstar)
and twice burned up the plate tank toroid operating full power RTTY on
40 meters. Twice!! $$$
I sold the amp several years ago.
Palstar has improved the design, so they say, and I hope that toroid is
included. If it isn't, I would not call that a brick-on-the-key 1500
watt amp. Do your research before you buy.
Other than that one weak spot, I agree, it's a fine amp.

## The plastar is a new version of the command technology amp. It comes
in 2 x versions.. HF-2500 and HF-2500 magnum. They are both rated for 1.5
kw
CCS CXR output . the ONLY diff is in the plate xfmrs. 33 lbs vs 44 lbs.
The plane
jane 2500 uses a doubler. The magnum uses a FWB. Both RF decks are 28
lbs.
$3995.00 VS $4695.00 $700 more for the 11 lb added weight of the 44
lb xfmr
seems like a bit much imo. I paid $1475.00 for my 253 lb, 16 KVA CCS
dahl plate xmfr.
I also have a smaller 44 lb dahl xmfr... $400.00
http://www.palstar.com/commander_hf-2500export.php Now u won't find this
amp anywhere
on their site, nor in their products guide. I found it with google..so it
exists..just no link to it from their site .
## $6495.00 120 lbs 2.8 kw out. 3 x holer called a HF -2500E
All 3 x amps are chockfull of T-2252B torroids..which are 2.25" OD x 1"
thick. They stack 3 of em on 160m. 3 of em
will handle 1.5 kw RTTY on 160m.
