Hi all,
Thanks for all your ideas and encouragement.

I'm not quite sure yet what to do about the tube mounting.

Yes, it had mains EHT originally and the mounting points for the EHT transformer etc have been used in the past. For now I will restore it as it is, with a view to converting it back as soon as I know the transformer rating etc.

I spent friday night at my parents house and went hunting for parts.
I now have most of the valves I need and many other parts, some of which are shown in the first photo.
I found 3 UU8 valves!, but only one PEN46 and it does not look too clever.
I did not have any 6F12 valves, so I will have to fit EF91 valves for now, which hopefully won't affect the alignment too much. Luckilly it looks like the RF coils have never been got at and I don't intend to touch them either.
I could not find a 10" speaker unfortunately.

The second photo shows a new MW31-74 CRT. I still need an ion trap magnet for this.

The third photo shows the anode cap adaptor which Heatercathodeshort kindly sent me. This allows me to use a later CRT without changing the anode connector.

Restoration has now started and is continuing on several fronts simultaneously. However, I shall write it up chassis by chassis. The aim is to get the sound working first.

Cheers
Andy
