I might follow suit there, Hugo. I have found a source of some axial types to mil spec M39003, and will use 1uF values rated 75V as just part of the decoupling design to replace what failed.
I'm also on the hunt for bigger values; there seem to be a lot of ex-Soviet bloc types that are NOS or pulls from military equipment but the unit cost is very high indeed...
