Nice Tv
I’ve got the Bakelite cased 7VT2, very similar inside to your set! Before I could get anything sensible from mine I had to replace the wax paper caps rated 6KV, the ones connected to the centering controls and the EHT smoother. I still have the selenium rectifiers fitted in mine, and although they are working they do occasionally let off a bit of a bad smell! Normally when the set is switched on from cold. Might be worth pulling the ballast tube out and checking that all the sections are OK. What I did with the filter caps was to cut them open carefully and remove the innards and replace them with a new capacitor, then stick the can back on. Although if new twist lock cans are available, I’d go with that instead!
Just Radios have all the 6KV rated capacitors for sale, good quality film caps too.
