[ARC5] Airpax power supply

[Robert Nickels]

Once again I seem to have found an oddball piece of gear with an even 
more oddball modification.   In this case, it's a synchronous vibrator 
power supply that replaced the B batteries in a portable 
transmitter/receiver made by an as-yet unidentified company but which 
looks similar to low-power AM field radios made by Morrow, Humble, 
Spilsbury, etc.

The power supply is model A-1064  made by Airpax Products Co.  for Air 
Associates (their p/n RD-13520-4).   The vibrator is Airpax p/n A-1130 
and is marked as 6V 400 cycles.   It is in a sealed metal can with an 
octal plug that fits into a socket on the end of the power supply 
module.   The supply is clearly meant for airborne service and thus 
would be kind of neat to get working although as of yet I haven't made 
any of those good vibrations happening.

Realizing it's a long-shot I just wondered if anyone might have come 
across a similar power supply?
