The idea of getting it going (first light) with minimal component replacement is to prove the critical parts, CRT and LOPT for example, are all working. I am not sure how experienced you are but fault finding a set where the wiring may have been disturbed or replacement components accidentally wired to the wrong pin is very difficult.

I would go for the minimum of parts replacement in the line and frame stages and try it, just don't leave it running for long. Once you have a reasonable raster you can complete the full restoration.
