I don't have any spares in the junkbox, but AES has them for a couple
dollars each.

If you replace them with a zener string, it will cost more than an OC3
replacement, but it will be quieter. Adding a 1uF film bypass to the
zener string, as close as possible to the caps, and putting the whole
thing in a metal can can really help noise.
