Only the best for FuzzDog's customers. Most 1N34A diodes that are readily available (including those sold with the kits) are of modern manufacture to meet a demand. Nothing wrong with that, but for added mojo points you can now easily get hold of some prime, vintage NOS real deal beauties.

This is a one-off bulk purchase, so grab them while you can. When they're gone...
Please note - these are very delicate, and care must be taken when bending the legs. Always hold the leg with needle-nose pliers close to the glass body and bend the leg from the other side. Never bend the leg in such a way as to apply any stress to the glass case. Use a heat sink when soldering.
