Yeah, that diode and cap are toast..
its a bit hard to find replacements using part numbers from a 50+ year old list, ( the resistor is easy ) i have picked mouser # 80-PHE450SB4220JR06 for the cap, and 625-RGP25M-E3 for the diode, i should prob replace that big cap and the little .001s on the screen pots, but they are most likely OK |

This diode has a faster recovery time and is better suited for rectifying horizontal rate AC, and also has higher reverse voltage rating (Which can save your bacon if the ~4KV DC focus ever arcs over to the adjacent screens that are driven from boost). https://www.mouser.com/ProductDetail...OsoE%252B4c%3D This is what I would buy if I were looking to replace those parts in my set.
