Bob Paquette's Microphone Museum is a private collection started in 1950 and displayed since 1970. It is the result of a continuing research into the history and evolution of the microphone. The museum contains over 1000 microphones, the majority of which are pre-1950. Many items associated with microphones and their use are also displayed. This includes many types of desk and floor stands, microphone enclosures, transfomers, preamplifiers and test equipment. On file is a collection of specification sheets, patent copies, catalogs, advertising literature, technical papers and copies of articles that appeared in early books, magazines, and technical periodicals. Three displays are set up to show the service and re-building process of the early carbon and condenser microphones along with the special aparatus used. Since the microphone evolved from the telephone, a variety of telephone transmitters are on display along with a few early telephones. To make the museum more interesting, early wireless and radio are also included.
