Emission Labs Tube Base Glue
Everybody, working with older type tubes knows the problem, the base can get loose, and fixing this is not as easy as it seems.
If 
you ever tried to glue a loose tube base, you probably found it does not hold for a long time. That is because almost no commercial glue will stick to hot glass for a long time. A risk you may not be aware of, is two components glue in many cases breaks the glass after a longer time. That is because old glass after longer pressure at the same point, will develop a crack. This is why historic glue becomes flexible when hot, and adapts to the glass shape. That is the magic of this old glue. Unfortunately when cold, it becomes brittle, and may become loose over time. Mainly caused by pulling the tubes out, by the glass. The glue we offer, contains original, historical tube base glue. We have found a way to modify it, so it can be used at home, to attach a loose tube base. It is flexible, and can be used, when there is still some part of the original glue inside. The original glue will be partially solved and build a strong compound with the new glue.

This picture shows how the Emission Labs repair glue forms a compound with the original glue.The original glue is the black particles that you see.They get weak again, and are soaked with the resin solution.NOTE, it is not normal to take off the socket; we just did so to look underneath, and see what happens.This is an old GECO rectifier tube, with almost no old glue left inside anymore.Only showed here to demonstrate how the old glue is weakened again. When using the glue, you should leave the socket on.
