All resistance measurements, except those
made from pin 3 of Vl1 and V12
(EZ81 rectifier),
are
made with pin 3 of V11 and V12 grounded.
All voltage and resistance
measurements are measured
to chassis with the controls set as follows:
INPUT SELECTOR to
PHONO, FUNCTION SELECTOR
to STERO NORMAL)' LEVEL at
10, BASS, TREBLE & FOCUS controls at O. For voltage measurements
at 14W output
, set the input selector to the PHONO position
and feed a O. 0035volt
(;3. 5mv) 1 kc
signal to the CH 1 &
CH 2 Mag. Phono Input jacks; connect a resistive (preferably non-
inductive)
load to the output of each amplifier, of equal resistance to the tap selected
(::1:20%), and
capable of
handling 15 watts. Voltage measurements are made with a
VTVM. Operating line voltage atwhlch
voltage measurements are made is 117VAC, 60cps.
NOTE: ALL VOLTAGE &
RESISTANCE VALUES
NORMALLY BY::I:15%.
