Thanks for the encouraging comments guys.

I think it’s actually quite comical to see new smoothing caps tacked onto the bottom, then one side cut out then replaced by different ones, which have been disconnected on one side and replaced by even newer ones... almost like you can physically see how long it was in service for.

Yes now I’ve calmed down a bit, reforming the old tired caps aren’t as much of a good idea as I might have guessed, although I must admit, I have had luck before after physically heating one of those Metal cylinder Metal cylinder type TCC ones with the holes on top.

I’m sure there’s enough space underneath, to mount RS ones, or better still, restuff what I can.

I took sometime to inspect the DC resistance of the focus coil and scanning coils. All appears well. I removed them and the CRT, gave it all a could clean, being cautious not to wreck the Emiscope label...

My tube appears to have odd rings around the face of the tube. Perhaps this is how they just were back then, seems a little weird to me. Also, Is it right that the face of the tube is right up against the glass? Makes me a little nervous...

Unfortunately a fellow collector friend was going to come up here to Guilford next week and collect the cabinet to restore it for me. Obviously ensuring he preserves all of the original finish as possible, but since we are in lockdown now, I can’t see this happening as it isn’t safe - I’m too nervous to attempt any cab repair on my own, souly because of its rarity.

The power switch appears to be 2 poles? Appears to be open on both sides unfortunately. I might have to bypass this for testing purposes when I run it up on the variac later this week.

Light dusting and cleaning, checking of IF coils, and TXs is a priority at the mo.

Thank you Rambo1152 for sharing this. The owner of the museum, Stella, was given the TV set by her husband Dave, for their first Christmas together. That was 35 years ago. It was a very sentimental part of her collection and was hard to part with it. I’ve promised to put it back to its former glory for her, and enjoy it as much as possible.
