Regarding the big electrolytics on the HT line, with the quality improvement in those components over the last 30 years, and the low price of replacements, it wouldn't make any sense in looking at the old ones; just leave them or get some good quality new ones, preferably from an established supplier. Vishay components from RS would be my go to place for both the 470k resistors and the capacitors. With the reduction in physical size, some people have fitted components of larger capacitance; I wonder how that impinges on diode ratings?? People seem to have gotten away with it.

Variacs, nice to have but have got a little pricey to buy. I only use mine on my 530 when it has been silent for at least a month or two.
