There should be a strip of felt or a plastic sleeve around the ion trap magnet to prevent scratching the glass of the CRT neck when its adjusted or removed. If its missing you'll have to fabricate something. Missing valves probably mean they've just been 'robbed' for another set at some time....common when a set was written off or perhaps the set was just pensioned off because the owners bought a new set. Such sets just became 'parts donors'.

You need to position the ion trap correctly, there should be an arrow on it which should point to the front of the set when on the neck. A good starting point is about half an inch from the Bakelite base with the magnet aligned with pin 11 or 13 of the CRT base. You then rotate the ion trap gently in either direction and also forward or backwards....the idea being to obtain maximum brightness on the screen. If it is incorrectly adjusted, it can cause 'ion burn' which shows up as a darker patch in the centre of the screen.

As HCS said in post #2, you need to do minimal work initially just to get the set in a position to apply mains and hopefully something on the screen. Basically you need to establish if the line stage and CRT are viable first...'First Light' even if it's a frame collapse or even a faint raster is important. No point in spending loads of time changing caps first if the LOPT or CRT are U/S.
