Dave:

	If you haven't found what you want by the time you get this, let me
know and I'll send you enough to get you started.  Those tubes were
intended for ~15 kV hard-tube magnetron pulsers, and take an awful lot
of drive.  I suspect they would be interesting for a self-excited VTTC
using a rectified NST or set of MOV's for power supply.
