Grounding
CAUTION
DO NOT DISCONNECT THE THIRD WIRE ON THE POWER PLUG. THIS WIRE GROUNDS THE
AMPLIFIER'S CHASSIS TO PREVENT A POSSIBLE SHOCK HAZARD. IF AN ADAPTER IS
USED TO CONNECT THE PLUG TO A TWO-PRONG SOCKET, MAKE SURE THAT THE AMPLI-
FIER'S CHASSIS IS CONNECTED TO A PROVEN EARTH GROUND.
INPUT CONNECTIONS
The input is unbalanced. The input screw terminals are labeled "COM" (-)
and "INPUT" (+), respectively. The terminal strip is located on the lower
right corner, as viewed from the rear of the chassis. The signal source should
deliver at least 300 millivolts into a 13-kilohm load.
Route the input cables as far from the speaker cables as possible, to
prevent coupling.
OUTPUT CONNECTIONS
The output screw terminals are located on the upper right corner, as
viewed from the rear of the chassis. The following illustration shows how the
output transformer's split windings are connected with a factory-installed link
for most applications (for applications with the link removed, see "Split-Cen-
ter-Tap Operation," below).
