Re: My first foray into Old model TV repairs.
I'm with Chris on this one, does look like a scratch, maybe done by twisting the trap magnet before its removal (though not sure how)?
Once a set is retired, it does become a parts doner so the odd valve may be taken. Just cos the Lop stage bottles have been half inched doesn't necessarily imply a duff lopt.
It may be worth running current through the LOPT primary for a few days to help drive out moisture and give it a fighting chance.
If heater glows correctly and you can get arc from the EHT connector then I think there is every chance for this to be a worthwhile project, the chassis looks clean. Peoples opinions vary, but I would change the coupling cap to the LOP bottle's grid and also the boost cap, give the best chance of some EHT - you can just tack them in temprarilly and return to stock if the worst happens.
TTFN,
Jon
