[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.
