Check Econco and get a 3CX2500H3 induction heating triode.

http://www.econco.com/specs/3CX2500H3.htm

Even though rated at 2.5kW, with forced air cooling is good for 4kW anode
dissipation and 10kVA to tank.  Rated at 6kV DC, and since is a "concentric"
design tube, may be able to be "debarnacled" to higher hold off voltage.
Peak plate current is very high (order of 10-12A!!!)  Low mu tube and
ultra robust for VTTC service, designed for 10kVA air cooled induction heating
service.

Price tag for a rebuilt tube is < $1k.
