[Milsurplus] PE-104-A Power Unit Vibrator Help

Dislexia strikes!  The low voltage version is for 3-18 volts not 3-13, 
the high voltage version is for 12-38 volts not 13-28.   The low voltage 
one is fine for 6 or 12 volts, the high voltage  for 12 or 24 volts.  If 
the ability to operate the DY-88 on 6-12-24 volts is desired, it would 
still require  both versions of the board.
