[Milsurplus] GRC 9 power question

[mac]

Greg,

As others have mentioned your best option would be a DY-88.  Next  
might be a DY-105 operating off a couple of 12 volt car batteries in  
series.  Another option would be the PE-162 MG set.  The same "if you  
can find one at a reasonable price" caveat applies to all,  
unfortunately.
