High Power HF BA's?

[kd4e]

I have been gathering info re. HF rigs with
hight power output, minimum 450W PEP Output.

The four rigs below appear to meet that criteria,
are there others?

Hallicrafters SR-400A
National NCX-1000
Swan 700CX
Yaesu FT-DX570

Two additional questions:

1.  Has anyone heard of a conversion of these
     rigs to a single GI-7B as the sweep tubes
     become unaffordable or unobtanium?

2.  Has anyone heard of a modification of these
     so that the final RF amp stage may be used
     as a SSB amp for an external exciter?

3.  Is anyone aware of one in decent cosmetic
     and operating condition for sale?
