[sdiy] Tantalum alternatives for re-capping?

[Colin Hinz]

Hello all,

Slightly off-topic, but I am re-capping an old (circa 1977) MXR Digital 
Delay and am wondering about the numerous small tantalum capacitors that 
are in this unit. Should I leave them be? Replace them with new solid 
tantalum parts? Replace them with some other technology?

Unfortunately the replacements need to be through-hole parts, which 
rules out some of the whizz-bang technologies touted as tantalum 
replacements, such as niobium oxide.

Thoughts?
