Sauereisen cement is still available. See www.sauereisen.com under cement
products, air dried.

I have also had success with high temperature silicone gasket cement, the
red stuff. It is available at any auto supply store.

No matter what you use, it will have to handle the heat. It is not clear
that the cyanoacrylic materials (such as Crazy Glue) will hold up under the
temperatures to which power tubes are subjected.

Thanks a bunch for your input guys.

Tube caps and bases used to be cemented with high temperature frit-type
cements. Sauereisen cement or a mixture of litharge and glycerine used
to be popular. The same sort of things that are used to cement bases onto
light bulbs today.
