Sony C-37A Microphone Restoration

By Mike Borish September 2016

sony-c-37aI just finished restoring a beautiful pair of Sony C-37A microphones. This is a very versatile microphone based on a 6AU6 cathode follower design. These are some of the earlier hand wired models. They are capable of both cardioid and omni pickup by opening and closing the small port on the rear with a screwdriver. Everyone from Frank Sinatra to Jimi Hendrix used this microphone in the 60’s. They’re still popular today and are rapidly going up in price.
