[Boatanchors] R-22 question

[Paul Sokoloff]

Hello all,
    I recently purchased an Aircraft radio corporation R-22.  This 
units' configuration does not agree with the decsriptions found on the 
popular web pages.  It has no dial and uses loctal tubes.  It has one 
large 12 pin connector on the front and a place for the standard 
dynamotor.  The coil pack inside says .54-1.8 MC.  The IF is 239 Kc. 
 Any info (schematic) and source for the connector would be appreciated.

Thanks,  Paul Sokoloff  WA3GFZ
