I just recently unloaded a II here in Tulsa.  Fortunately for me, my
video died earlier, and my local Kaypro dealer replaced the video board
and the tube.

My understanding of the kaypro II video is that there are several types
of tubes in II's, each requiring a matching video board.  Therefore, the
first thing I would do would be to try to find an exact replacement tube
from an electronics parts place, assuming that a voltmeter says that your
filament voltage and high voltage are still intact.

If this fails, there is an outfit which advertised in the Kaypro mags
called ERAC which carried spare parts, especially video.  Sorry, I don't
have any further information about them, except to say that you might try 
calling Microsphere in Oregon to get additional hardware type help or
phone numbers.
