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.
Ron, I just now saw your thread on your 690. Sure brought back memories of restoring that 38-116 that I bought from you many years ago. My 116 had the same hacked up tube shield bases. Luckily Gary Schneider of PTOP had some NOS Philco tube bases in stock that I was able to purchase at the time.
I also recall having to use a Dremel to slightly enlargen the hole in the repro dial that I purchased from Mark Oppat.
Here is the article about my 38-116. That article was written a while back and my restoration skills, as well as my writing skills, have vastly improved since then. I see quite a few things that I would have done differently today.
