I believe it's been spelled both ways, Stu. I couldn't decide, and picked one.

In woodworking applications, I hated the stuff.

Aloha,

I have sucessfully used Weldwood Plastic Resin mixed to a paste with alcohol for faster drying. Use of a hair blow-dryer makes it faster still.

Default Repairing Octal Bases

I have two 6V6 tubes, a 1951 RCA and a 1959 RCA, that I successfully repaired using aquarium sealer. I use a small flat-tip screwdriver to force the silicone into the gap between base and envelope. I then clamped the tube together and let it sit. After a day, I took a razor blade and trimmed off the excess silicone.

These tubes tested great and I didn't want to toss them. The 1959 was so loose that when I had it in the tester it would die if I slightly twisted it. I marked the position where I had connection and reglued it in that position.

To my way of thinking, the silicone isolates the base from the envelope, possibly reducing vibrations from the chassis that might cause microphonics.

I've used the JB weld epoxy, push into the joint and wipe clean prior to standing upright with book on top to weigh it down in place. I also used it for loose top plate connectors.
