I can't seem to get the link to work with the pictures, so I don't
know what the tube looks like, but sticky fluid is NOT an indication
of a problem with the tube. Some tubes used a bonded safety glass, and
that goo leaks out over time. But I've never seen a VT100 with such a
tube installed. The most common cause of goo on the tube is going to
be goo surrounding the 2nd anode connection (the suction cup). This is
the plasticizers leeching out of the anode wiring, and gooing up the
tube. The cable will be all sticky too. You can clean it off, I find
that brake cleaner will dissolve it nicely. Just clean the area around
the connection, don't clean the graphite coating off the main parts of
the back of the tube - scrub only the clear glass areas.
Without knowing what parts you have, I can't really tell you more than
that, but, in general, I find that VT100's tend to work fine. There's
nothing special I would do, just hook everything up and try it out.
You're not going to blow anything up, assuming you've got parts
