Ribbon Microphone Service
We have been replacing ribbons in the RCA 74B and 44 microphones for a few years now, and are now offering this service to the public. We are only offering the service for these two mics at present due to the tooling that forms the ribbons is specifically designed for these mics. Rather than just an even ripple amplitude in the ribbon, we have designed 3 different ribbon forms that use even, convolution, and random ripple amplitude. The convolution we found reduced the tendency for the mic to have a sharp resonant frequency based on the ribbons length. We may expand to more mics in the future if we get enough interest. Please contact me directly and we can talk about your mic specifically, some mics need a ribbon, some will need more involved service.
