[Amps] Cheap 1500 Watt Amps?

[Dan Levin]

I'm thinking about outfitting my contest station with 6 amps, one for each
HF band.  I want amps that will put out 1500 watts reliably, and that are
cheap :-)

One option appears to be the Dentron MLA-2500.  They are available for
~$500.  It appears that it might be possible to re-tube them with either the
3CX800A or the 4CX800A, probably with a transformer upgrade, and get them to
put out 1500 watts.  Then again, maybe I am dreaming and the power supply
and output circuits would not deal well with 1500 watts :-)

Maybe 3 tube Alpha 76PA's are a better option - I already have one and it is
rock solid.  At $1100 or so, they might be cheaper than the modified
MLA-2500's anyway.

What would your suggestion be for a low cost, reasonably reliable amp that
will do 1500 watts out in contest use?

Thanks much!
