    BEFORE THIS AMPLIFIER IS PLUGGED IN, make sure its rated voltage corresponds to the voltage of the AC power
source to be employed. Failure to use the correct voltage could cause damage to the amplifier when the AC power cable is
plugged in. Do not exceed the rated voltage by more than 10%; operation below 90% will degrade performance or cause the
unit to shut off.

      A) Insulation Resistance Test

          With a 500VDC Insulation Tester, Check
          insulation from the outer metal contact of the
          RCA jack (chassis) to the line neutral of AC
          cord. Resistance should be >100M.

      B) Hi-Pot Test

        If a UL approved Hi-Pot tester is available, test
        line & neutral of AC cord to outer shell of RCA
        jack (chassis) at 1100VAC for 2 seconds.
        Observe all of instrument manufacturer's
        instructions and safety warnings in performing
        this test.
