Any post war Television Repairmen here?

Be DAMN careful. High, deadly voltages in there. The big wire to the side of the CRT is thousands of volts, and that CRT is a VERY efficient capacitor. It, the CRT, can retain a deadly HV charge for MONTHS

First thing you need is a diagram/ schematic. ANY electrolytic cap is immediately suspect. The smaller caps are likely what are called "paper" meaning, two pieces of foil (the "plates") wrapped with oiled/ waxed paper of some type for a dielectric, dipped in some form of beeswax/ etc for a case. There is a "sort of" guide online for modern caps to replace the paper ones

For electrolytic, buy commone grade modern replacements, as close to the capacity (microfarads) as you can get with AT LEAST as much (or more) voltage rating.

Modern caps are generally smaller than the old ones, and you can sometimes "gut" the old metal cans and put the replacements in the old cans
