Why no love for this GE roundie ?

A few questions question:

I'm trying to order the electrolytics for the cans, and a card board electrolytic on the audio / video output / agc / sync separator / sweep board.. Assuming that's the right board to replace all the film caps on also and get the vertical height and centering in better range..

Sams shows the cans with different sections.. I'm not sure if it's showing a rating for each cap in those sections.. Some show a square and triangle symbol.. I'm not sure if it's showing the microfarad of each cap..

C3 is on the board mentioned above.. Looks to be a one section.. Shows 50 and 150 volts.. I'm assuming it means 50mf / 150volts.. Chart also shows a dot above Cap.. So I'm not sure.. I select 50uf 150volt electrolytic caps in mouser and I only get a handful of side mount caps.. and this one in the link would be the only one i could get seeing how mouser has a set minimum for the rest

I did the Mallory part number search on Google and came up with this site

I assume I must be correct. on how I'm reading the Sams.. I guess if this site has this value.. I might as well get it from them seeing how the correct part number will mount correctly instead of ordering a random cap that mounts different..

I'm also typing the values for the 4 section cans into mouser and I don't get very much.. Another cap like in the mouser link above and they want $15.80 for one cap.. Not sure if there is another source to get these elctrolytics other than mouser and digikey, and bottom mounts would be better for the cans..

The ceramic disc caps on the sams don't show voltages for any of them.. Should I worry about replacing those or just the film and electrolytic caps?
