How about leave the defective 50k above chassis for originality, snip the wiring below and add a modern replacement under chassis? It's no more sacrilegious than changing caps. The filter choke, who knows, you'll find out if it's good once you trace the wiring or fire the set up under load. These things are so old that the copper wire used had impurities along with not so good insulating varnish which allows the wire to oxidize and corrode open over time. Same issues with the stage coupling transformers. The finer wire winding's are most subject to corroding open.
