Feed the test signal into BOTH inputs. Using an AC voltmeter connect it to one channel of
the amplifier and note the reading. Set the balance control to centre. Then connect the
voltmeter to the other channel. Hint keep one lead of the meter to either ch1 - or ch 2 +
speaker terminals as these are common ground. Then you can simply “poke” the other
meter lead into each of ch 1+ or ch2 - speaker terminals.
Then set the BALANCE control until the readings on the meter are the same when
“switching” between ch1 and ch 2.
