Seems to me that if it really is an overgrown 3CX1200, there are a couple 
of major advantages -- the robust grid (no need for a grid trip) and the 
instant-on filament -- no more 3 minute wait.

It would be interesting to know if the drive requirements are such that it 
can be driven to the legal limit by a 100-watt exciter, because I 
understand the 1200 is a bit marginal at this level.
