4kV on the anodes will so 1500w out.  However, Class C places an 
unsymmetrical load on the exciter.   You may have some SWR problems to 
resolve.  If you want it to oscillate, do not neutralize it.

No

Probably not unless you are expecting a ufo to pop out from behind the 
Hale-Bott comet with an extensive selection of amp parts at 1970s prices.
