Anyone know enough about these to offer pointers or

Triac....

Google it.

Thanks, I would (given my luck) spent a couple of days
googling before I stumbled across a repair. Now to find
a triac.

Okay, I've done it for you. (It's been a while since I played actively
with this stuff...I was curious.):
From the FAQ for the comp.home.automation newsgroup at
http://techsupt.winbatch.com/TS/T000002007F31.html

"Q508. How do I repair a "blown" X10 lamp module?

X10 lamp modules have a bad habit of dying premature deaths. Most of the
time, the problem can be traced back to a bad triac. Why the triac is
the weak link has been debated hotly. It is possible to "resurrect" the
module by simply replacing the triac. Caution must be stressed here;
there are a lot of triacs available, but whichever one you use must have
an isolated tab. The most universally available replacement is from
Radio Shack, part number 276-1000 [Does this part actually have an
isolated tab?], or Digi-Key part number L4008L6-ND. In addition to
having an isolated tab, it also has a higher rating than the original
one, so will be less likely to fail.

If you don't know a triac from a mouse trap, you'd better not try to
replace it."
