Capacitor size

Working on a Stewart Warner R-1254 that has two 12uf/600v filter capacitors. Can't find this exact value anywhere in 600V. I can get a 10uf or a 20uf at 600v. I don't want to drop down in voltage so do I go slightly less at 10uf or do I almost double the size to 20uf? I could double up and do a 10 and a 4uf for 14uf.
Any advice on this?

Iwuld not go 20% above or below. This place will have thenhttp://www.vacuumtubesinc.com

You can go 450 volts will be fine.

Hi the 10 or 20 will do fine.Stay with the 600 volts never go lower voltage.I would use the 20 @600 v ...The 10 will work with a bit less filtering.Todays caps are much better than what they had back then.Sprman : )

Thanks for the input on this. I'll stay at the 600v and try the 10 and 20 and compare the two.
