[GreenKeys] WE Audio Amplifier KS-16610: Info/BSP?

[Richard Knoppow]

    Some of the D-spec stuff I've seen was nearly identical to 
the standard models but may have gone through additional QC. I 
don't know. An example that is at hand is a microphone D95921, 
this is a WE 630A, the first moving coil microphone to be made 
commercially. Its a motion picture version differing outwardly 
from the 630A in being finished in black wrinkle rather than 
baked bronze and having a Type P connector rather than the 
special connector supplied on the broadcast and public address 
versions. There do not appear to be any internal differences but 
there could be small performance differences which are not 
apparent. I also have a pair of WE moving coil headphones but I 
don't think there was a commercial version of them. Similar 
phones were listed as accessories for WE broadcast consoles under 
the D spec number. A lot of the WE sound recording apparatus has 
D spec numbers. My retired Bell Labs friend told me a great deal 
of inside information about WE, Bell Labs and ERPI but I never 
wrote anything down. Too dumb.
