Hi Ed,
That's a great tube.
Regarding tube burn protection, I've found that if you are in TV mode and you use the on/off volume control to switch off the set, all is OK. If you simply switch straight back to radio from TV mode, that is when there is a problem, so best to stick to switching off the set before you go back to radio mode.

I'll dig out some pictures of the cap restuffing later. I've not written a thread on the set in question as the owner does not want to advertise exactly what type of set it is.
When it is finished I might write a joint BVWS article together with the set's owner.

Cheers
Andy
