after disassembly.
(3) Extension cord : EXTKSRT002-18P ( 18 pin extension cord ) For connection between mechanism assemblyand main board.
(4) Check for mechanism driving section such as motor ,etc.
3.6 Disassembly method
(1) Remove the front panel assembly.
(2) Remove the bottom cover.
(3) Remove the front chassis.
(4) Remove the heat sink.
(5) Remove the rear panel
(6) Remove the main board.
(7) Reattach the heat sink with the two screws B. (Refer to Disassembly method.)
(8) Reattach the rear panel with the screw E. (Refer to Disassembly method.)

(10) Confirm that current is being carried by connecting an extension cord jig.
NOTE:
Available to connect to the CJ601 connector when installing the front panel.
CAUTION :
Be sure to attach the heat sink and rear panel on the power amplifier IC and regulator IC of a main board when supplying
the power.If voltage is applied without attaching those parts, the power amplifier IC and regulator IC will be destroyed by
heat.

(2) Load VT703 (10kHz) and play it back in the forward
play mode. Adjust the Rch and Lch output levels to
max, with azimuth adjustment screw B. In this
case, the phase difference should be within 45 .
(3) Engage the reverse mode and adjust the output
level to max, with azimuth adjustment screw
C.(The phase difference should be 45 or more.)
(4) When switching between forward and reverse
modes, the difference between channels should
be within 3dB. (Between FWD L and R, REV L and
R.)
(5) When VT721 (315Hz) is played back, the level dif-
ference between channels should be within
1.5dB.
(1) Check to see if the reading of the F, counter / wow
flutter meter is within 3015Hz to 3045Hz (FWD/
REV), and less than 0.35% (JIS RMS).
(2) In case of out of specification, adjust the motor with
a built-in volume resistor.
(1) Play test tape VT724, and set the volume position at
2V.
(2) Play test tape VT739 and confirm.1kHz / 10kHz: -1
