4. DISASSEMBLY
PROCEDURES
Front PanelAssembly
1. Remove the bonnet case by unscrewing the
three screws on the rear panel.
2. Unscrew the two screws @ frotaing the front
panel assembly in place and remove the four
rotary knobs.
3. Press down on the three hooks on the front
panel assembly (indicated by the three arrows)
with a screwdriver to release the panel holder
and lock. Then, gently pull the panel outward.
(The bottom of the panel assembly is also
Iocked in three places by hooks, so remove the
panel very carefully.)

6. CIRCUIT DESCRIPTIONS
Equalizer Amplifier
The equalizer amp uses a low-noise IC (NJM
4558DX) that contains both the left and right
channel circuits. This IC uses a balanced positive/
negative power supply to permit the more than
sufficient permissible input level of 150mV (at
1kHz, 0.017dTHD).
PowerAmplifier
This all-stage direct-coupled pure complemen-
tary SEPP circut features a differential amplifier
in the first stage, and incorporates the tone con-
trol circuits in the NFB loop.
The power stage is a complementary 2-stage
Darlington connection, resulting in an output
power rating of 35W+35W (8Sr, 20Hz-20kHz),
harmonic distortion of lessthan O.O\Vy.
