[Amps] Commander HF-1250 problems

[Doug Ferguson]

I'm new to HF amps. and have a couple questions about a Commander HF-1250. I
just bought

one, used of course, with no manual.  Found one online and it says the plate
current at idle

should be about 2800V.  My meter is reading about 1800V and I'm only able to
get about 850W

output on 20m CW with 60w of drive.  The specs say I should be able to get
1000w out with 40-60W

of drive.  Does anyone have any experience with this amp and do I have a
problem somewhere?

I'm also using the 120v setting.  I would like to use the 240v setting but
the jumper block on the back

doesn't match the diagram in the manual.  Mine has 6 terminals on it and the
diagram only shows 5.

Again, would anyone know how to wire this thing for 240v??  And finally,
does anyone have the 

factory data sheet showing the initial tune/load setting for each band so I
have a starting point for

tuning it up?  

 

Thanks for any help!!
