Take it from a guy (Me) who just restored a DuMont RA-105B7 "Sussex" from the Ground Up...You are One Lucky Stiff.
Mine had a Raster when I first got it, even though it was sitting in a Basement for 40 years, unused. But, I never turned it on again until I recapped the entire Set, replaced a few WW Pots & Tubes, etc etc etc.
Some of the Electrolytics are replacements. If it was my Set, I would bench it and check out all those (potentially) leaky Caps, dried up Electrolytics, etc.
If one of them Blows, you might have a catastrophie on your hands.
It's working now, I know. But, why take a chance?
If I were You, I would get someone who knows what they're doing. I wouldn't delve into this as a "First Project." You'll probably ruin something.
The Chassis Bolts are no Big Deal. Easily replaced at any Hardware Store. The Star Washers that grip the bottom of the wooden Cabinet Shelf to the Chassis are probably not, but, some 1" diameter Washers will do.
BTW, the Local Newspaper, the Worcester Telegram & Gazzette, is doing a full story on my Restos, including the DuMont, complete with Photos. It will run Feb 11th, one week before the Analog Broadcast Shutdown.
Good Luck with the Televisor. I mean that. But, don't take it for granted that it will run like this forever. The odds are, something will let loose, or, something(s) are already marginal. If it takes out something made of unobtainium, you will kick yourself forever...
