Power and Grounding 
The 120 VAC line cord has a three-prong plug which should be plugged into a three wire grounded electric outlet.  It is 
very important to maintain the amplifier ground for safe and trouble-free operation.  If there is no grounded electric outlet, 
connect a wire from the GND terminal of the unit to a water or steam pipe.
