I've seen the heat shrink on a couple of Zaerix valves. I didn't realise it was a MOD thing, it looked like a Zaerix special.

I've used PVC tape to fix loose envelopes to the base of octals and I've had no problems. I've also got a rectifier which has been lashed up with masking tape and a few valves with old fashioned black tape. Taped up octals have never caused me any problems. You don't want the envelope loose, but on the other hand, if you can possibly help it, you don't want to extract a valve by pulling the envelope.

I've used Araldite to re-attach top caps and that's always worked.

I can see that the tape wouldn't do for valves prominently on display in an audio amplifier.

Pete.
