[Milsurplus] BC-221 question for the pureists

Correct.  Also, not all LM contracts had power supplies supplied.  Those with 
AC supplies were intended for ship or shore station use.  Some models (for 
aircraft use) were operated off of one of the radio receivers installed, such as 
the ARB.  The 5-pin plus guide pin male connectors on such sets are there to 
supply power to various accessories, including the LM.  There is a chart in 
the front of the later LM manuals detailing differences between models, and this 
is one of them.
