Question regarding capacitors

There are a few cans used in the 38-690 that might require electrolytic replacements.

For one, 30-2201 (8 uF 450V and 10 uF, 50V), I might be able to use film for both.

But another, 30-2249 (8 uF 475V, 3 uF 475V, 2 uF 300V) - I think film for all three might be too much to fit in one can.

And then there's one can on the tuner chassis, 30-2247 ( 2 uF 450V, 1 uF 450V X2, 10 uF 50V, 2 uF 300V). That's five caps in one can. I think I'll have to restuff that one wilth all electrolytics.

I think I'm going to use these for the three missing 8 uF cans:

For the 18 uF cap, I am thinking of using two Solen Fast 8 or 10 uF 600V axial caps in parallel, stacked one above the other inside the can. The Arcotronics/Kemet 8 uF axial from Mouser might not fit inside the can (diameter of the cap is 1.36" and the outer diameter of the can is 1.375"; inner diameter will be slightly smaller). The diameter of the Solen 8 uF cap is 1.18" which will fit much easier.

Solen caps have been ordered. I haven't ordered any of the others yet.
