Tokyo High Power used a pair of ARF1500 in their HL2.5KFX.

Two amps with those transistors were built in Germany:

For those interested, MIcrosemi has a line of relatively high voltage
RF MOSFETs:

One intriguing possibility with these is direct coupling (through an
LP filter and DC isolation of course) to 50 ohm coax. No transformer
needed. 

Something to think about.
