Kevin:
90% of the time the vt320's fail, it is this
transformer shorting out, which
takes the horozontal transistor(?) with it. It heats up, cracking open, and
spewing out it's magic ooze.
and Tony:
Alas not. Go back to the main board of the VT320 and
look at the flyback
transformer (the one with the thick red EHT cable to the side of the
CRT). Most likely it will be physcially cracked.
pinpointed the problem. My fever went down enough today (bad flu) to take
the thing apart farther. Just as predicted, the transformer in question has
an ugly-looking crack near the EHT cable, with Magic Spooge leaking out and
solidifying. Alas.
Eldest daughter and I took turns with the soldering iron and solder-sucker,
and got the busted transformer off. (The little spring-operated solder
suckers are actually pretty effective.) It says:

HI POTTED
Googling for a source for a replacement transformer is next on the task
list. Will also order a replacement for the transistor at the same time, in
case the transformer alone doesn't fix the problem.
My thanks and compliments to Kevin and Tony - I have no idea how you (and
the list collectively) maintain such an incredible knowledge base.
