[Milsurplus] BC-611 vibrator supply?

[WA5CAB at cs.com]

George,

I never heard of it.  And would add that I never saw a plug-in vibrator 
through the end of their use that was small enough in diameter to fit into either 
the A or B compartments.  All of the common standard ones are larger in 
diameter than a D-cell.
