Model AM-U11 (Refer to Figs. 9, 11)
Connect the load resistors (RL=8 ohms) to Speaker
terminals. Then apply a 1 kHz signal to the AUX
input terminals, adjusting the input level so as to
obtain the rated output voltage level (12.65 V) at
both ends of the load resistor. Adjust VR101 (left
channel) and VR101b (right channel) until the
Lever Meter reads 20W.
Model AM-U22 (Refer to Figs. 10, 11)
Set the Meter Range switch to “x1”, and connect
the load resistors (RL=8 ohms) to Speaker terminals.
Then apply a 1 kHz signal to the AUX input termi-
nals, adjusting the input level so as to obtain the
rated output voltage level (8.94 V) at both ends of
the load resistor.
Adjust VR3 (left channel) and VR3b (right channel)
on the Main Amp P.C Board so that the 7th LED
(10 watts) in the Power Meter lights up.
