[TMC] SBE Mic connector?

[Richard Knoppow]

    Thank you John, that confirms my visual identification. I 
happen to have a couple of other items with similar connectors, 
for instance a Barker & Williamson SSB generator. I also used one 
for some reason on a speech compressor I built a million years 
ago. They were bargain bin parts back then. My Electro-Voice 664 
microphone uses a four pin version of the connector, it functions 
as the impedance chooser depending on which pins are connected to 
the cable.
    Of course, at one time Amphenol was best known for those 
screw on coaxial connectors found on every public address 
amplifier. Hard to find now but must have been made in the many 
millions.
