It's limited by what breaks down, and the loaded Q of the tank. I 
can easily get ten times that amount using HV rated parts in a PA.

I've measured higher voltages in the 220, although even 3700 volts 
is enough to arc the air variable and bandswitch under some 
cases. 

People at home, tune up your PA's. Unhook the antenna and short 
the output port of your PA. Apply full drive, and tell me if you hear 
any sizzling noises or bangs in the tank or tube!  

If you have technical points, besides insults or childish things like 
zzzzzzz, I'll address them. As you know, I am not allowed in the 
mud with you.
