In this 38-690 restore linked above, I used two 8 uF 630V Solen caps in parallel to equal 16 uF to replace the 18 uF cap, and 8 uF 630V film caps to replace the 8 uF caps.

30-2201 was originally rated as follows: 8 uF, 475V and 10 uF, 50V.

I would not use 450V caps, especially taking into consideration today's higher line voltages. I would go with 500V, minimum. Or better yet, use as many Solens as you can - they should never need replacement again as long as you own the set.
