I SCHEMATIC DIAGRAM

('l'his schematic diagram may be modified at any
time with the development of new technology.)

Notes:
1. 31 : Onloff (power) switch.
2. S301 : Start switch.
3. 8302 : Stop switch.
4. S303 : Cueing control switch.
5. $304 : Repeat switch.
8. 8306 : Smed selector switch in "W position.
7. $306 : Record detector switch.
(It is detects the record on the turntable.)
8. S307 : Reset switch in on position.
(Upper cabinet is closed.)
9. $801 : Rest switch in "o position.
(Presently tonearm is on rest.)

10. 8701 : Record size detection switch.

H. The voltage value and waveform are the standard values of this
measured by DC electronic voltmeter (high impedance) and
oscilloscope on the basis of chassis. Therefore, the voltage value
and waveform may include some errors due to the internal
impedance of the tester or the measuring set.

:1 is the voltage when turntable is in step.

t l l is the voltage when turntable is in rotation.

' '- 4 is the voltage when tonearm is in lead-in mode.

' < > is the voltage when toneerm is in return mode.
12. Positive voltage lines.

'The part No. of diodes mentioned in the schematic diagram stand
for production part No. Regarding the part No. with 0 mark the
production part No. are different from the replacement pert No.
Therefore. when placing an order for replacement part, please

use the part No. in the replacement parts list.
