Fisher double wide version and power supply - world's first phantom powered ribbon mics
Shown here is the double version. I haven't seen the inside of this one yet. This has to be one of the rarest production ribbon mics - not something you would read about in ribbon microphone reviews!
5:03pm: Micha informs me that the ribbon is not double width, but it is a two ribbon arrangement, sandwiched for higher output. This is interesting since we just isolated the ribbon motor on the single ribbon mic, below, connected it with a Crowley and Tripp ribbon microphone transformer, and it produced a very healthy output! Also, the response of the mic is pretty similar without the amplifier, so that amp is fairly flat.
Actually, RCA labs and Harry Olsen made a number of amplified ribbon microphones almost as soon as the first ribbon mics were made, in the 1930s. These amplified ribbon microphones used multiple tubes located in the housing, which was quite large by today's standards.
