The Amperite Velocity Microphone
Continuing our review of Audio Engineering Magazine, today we will look at some of new offerings in microphones available to audio engineers in the late 1940s.
The Electrovoice 650 and 645. I really would like a nice 650… the ‘Jac Holzman Mic’
An Electrovoice line-up circa ’47
The Electrovoice Cardyne and Cardax
The Electrovoice V1 ribbon mic.

The EV Century is, I think, the mic in the little brown Conn Strobotuner.
Yes. They usually came from the factory in a ZAMAK case (maybe just zinc, though) that was highly polished. The version used in the ST-2 had a copper-ish colored paint that matched the Strobotuner case’s paint (actually a little darker, but close enough to let you know it went with the tuner). At some point, Conn may have started including the shiny ones with the tuners, probably to save money since I am guessing the painted ones cost them extra from EV. Or possibly all the polished ones I see with these old tuners are replacements? As a child using these tuners in school, I only ever saw the painted mics. However, as a professional orchestra musician, I have owned three of these tuners over the past 40 years, and three of them had the shiny mics. All four, however, were the EV 915. Regards — Wade

These are great, what’s really interesting the Amperite ad. The model numbers of the ribbon mics are very similar to the Reslo models and the PG Dynamic is practically identical to the Reslo.

I found an EV 650 in an old house. It still works too!

Would anyone know app. Value of this in today’s market- aged and broken cord
Thank you
