Hi, Dave.

If you have a schematic (OR manual) in pdf format, I would appreciate a copy!

I have a manual for the ARC Type 21A ADF circa 1962 which uses a P-14A Power Unit.

An obvious difference is the dynamotor is fixed on the P-14A not removable like the P-12 but perhaps there are some similarities in the electronics to be helpful to you.

73,

I got lucky!  Rummaging through my small collection of military connections, I found an 8-pin female "Cannon" connector with a stamp on it of 52A and it fits perfectly on the P-12!

It should be easy to remove the bottom plate and figure what I can do with it.  I hope to be able to build a switching box to be able to feed the dynamotor output one or more individual "Command" receivers.
