I have had good luck using both Super Glue and GE RTV silicone seal ( aquarium grade- as the outgasses from it don't harm electronic parts) to tighten up the bases.

As far as the grid/plate caps go, I found using furnace cement (Handles high temps very well) to glue the caps back on works well, and then silver soldering the wire back on to the cap if needed.

I personally know one "local" used tube dealer who uses Super Glue on all the ones he sells here in the States.
