RCA Model MI-6207 G Aeropressure

This interesting looking microphone almost looks like a pet dog or cat returning from the vet wearing the “cone of shame” — however there was nothing shameful about using one back in the day in a radio station or an amateur operator.  I recently sold this microphone on eBay for $102.  This link is a great resource for more information about this item: http://www.coutant.org/aeropres/index.html

RCA Model 77-C1

The look of the pill-shaped RCA 77 series of microphones is arguably the most associated with vintage microphone design.  Much has already been written on the subject, and I have to tip my hat to Gary Avey, “The Microphone Man” of the Modesto Radio Museum, who gives an excellent overview of the 77 series here.  The 77-C1 was actually three microphones in one, using two ribbons inside.  Another website also provides a detailed description of the 77-C1 with schematics and additional photos.  The item shown below is available sold on eBay for $1522.

RCA Junior Velocity, Model 74B

In the middle 1930’s, RCA introduced the “Junior Velocity” 74 series as a more affordable option to their popular 44 series of bi-directional ribbon microphones.  They quickly became widely adopted by small radio stations and recording studios, and continued to be manufactured until around 1950.  They have since claimed a seat at the table of the most desirable vintage microphones.  The item shown below is available recently sold on eBay for $405.
