Digikey doesn't have them at the moment, actually. They seem to be out of stock. Along with the rest of the world.
As Daniel says, you're going to be fighting quite an uphill battle trying to repair those. I think you have two options:
1. Beg, borrow, or buy any black or grey jaguars off of teams that are near you.
2. Switch to
VexPro Victor 884 Speed Controllers. There's loads of teams that swear by them anyways, and they're $10 cheaper than Jags. If you're not using the advanced functionality of the Jaguars, these will work atleast as well for you.
