Carbon microphone revitalization

It would be easier to put the entire microphone in the oven rather than just the capsule, but I am not sure on whether this could cause damages to the non-metallic parts I've never heard that, but back when telepehones uses carbon mikes, it was popular to fix them by removing the cartridge inside, and banging the cartridge on a table top. Geoff. Additionally, that procedure is a legitimate and it is intended to break up and separate the clumped up carbon particles. A frequent procedure for outside pay phones back in the old days. You would smack the mic on the metal plate under the phone. Paul P. |
