[R-390] (no subject) BSM Connectors

[Glenn Little WB4UIV]

The connectors in question are Automatic Connector RF-0700 series and 
are their BSM series.
The chassis mount is a RF-0730.
I have not researched the cable mating end.
These connectors are available from Surplus Sales of Nebraska at $25.00 
each.
Theirs appear to be the Amphenol equivalent MB series part number 47800 
for the cable end.
Kings made an equivalent connector in their KM line.
These connectors are obsolete and unless you can locate some from old 
stock, you will not find them.
These connectors were also used by Tektronix on some of their plugins.
