[ARC5] My mil phones - solved.

[Richard Knoppow]

    Correction:  I remeasured the Murdock phones I posted 
about yesterday. The correct DC resistance is about 320 
Ohms. The measured AC impedance is about 640 Ohms. These are 
constructed somewhat like the ANBH-1 with a small unit in 
the center of the shell. I don't know what type of mechanism 
it is. They are very light weight but have a heavy duty 
waterproof rubber Y cable much like some of the older Signal 
Corps headphones. They do not appear to be very old.
    FWIW, William Murdock had a patent on a way of 
manufacturing headphones by molding the entire mechanism in 
a plastic shell.
