Vince/Ira,
More or less the same here: I've got a pair of the slightly older MA 4224 audio encryption units, which also have the 5 white plugs and 15 socket options inside, and a 4.5v nicad potted in resin. This had gone short circuit and was pulling down the internal 5 v rail, so I replaced it with three small 225mAh nicads in heatshrink tubing.
I understand that the pins and sockets arrangements are to set the basic configuration up, and had been unplugged prior to government disposal of the units.
If working they should produce something like a white noise output, from memory, but mine don't produce anything: have actually got them on a shelf as bookends!
Rgds

Seconded, also :)
Were you able to get the things powered-up, Vincent? On application of
power, the only thing my units did, was light up all the LEDs and do
nothing useful......
