VT100 and/or VT105 rescued from scrap

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 connected properly. -Ian On Tue, Oct 20, 2015 at 12:11 PM, Lukas Kaminski <lukas.kaminski at krankikom.de> wrote:
