The highest B+ you can handle with a C4S in the traditional setup where the LED bias resistor is grounded is 375V - with an MJE5731 in place of the MJE350. For kV type B+ you should probably use a tube type active load. Or you could try IXYS fuses, I mean, chips, and drop the input voltage on the chip down to it's 450V max rating with a resistor or regulator.As long as there is enough compliance to allow the tube to go to it's full output swing without running out of voltage headroom you are OK. We haven't found that large amounts of headroom above that compliance level make much difference.
FWIW we are going to be doing a little more experimentation on active loaded output stages soon - on a lot smaller scale than a 1kV 845 amp...
