ON ...... Press this switch and the power will come
on. The ARM ELEVATION switch in-
dicator ( ¥) and SPEED switch indicator
(45 or 33) will both light up.
OFF .... The power will be cut off when this switch is
released, and the indicators will go off.
NOTES:
e The platter will not rotate when the tonearm is on
the arm-rest even when the POWER switch is set to
ON.
e Always set the POWER switch to OFF when you do
not intend to use your turntable.
AUTO SWITCH’ ">
ON ...... Select this position for auto play (refer to
page 10). When this switch is pushed, the
DISC SIZE indicator (12"'30) lights up.
OFF...... When this switch is released, the auto
mechanism is disengaged, and all the oper-
ations can be performed by hand. Set the
switch to this position when playing a
record whose size is not standardized since
the tonearm will otherwise return to the
arm rest automatically. When this switch is
set to OFF, you will not be able to per-
form auto play and repeat play operations.
For record play, move the tonearm manu-
ally.
NOTE:
e When the AUTO switch is set to OFF, the DISC SIZE
and REPEAT switch indicators will not light up even
if the respective switches are pushed.
Press the switch that corresponds to the size of the record
you want to hear for auto play operations. The corre-
sponding switch indicator will then light up.

NOTES:
e The 12''30 switch is selected automatically when the
POWER switch is set to ON.
© These switches will not work if depressed when the
tonearm is moving (auto return).

REPEAT SWITCH
Press this switch for repeat play. When pressed, the indica-
tor will light up, and the record will be played again (refer
to page 11 for further details on repeat play). Press this
switch again to release it. The indicator will go off and the
repeat play function will be released.
NOTES:
e This switch cannot be operated even if depressed
while the tonearm is moving out of contact with the
record.
e There will be no repeat play when the AUTO switch
is set to OFF.
START/STOP SWITCH ~~
Press this switch for auto play. The platter will start to
rotate, the tonearm will automatically move over to the
edge of the record and play will begin (auto lead-in).
If this switch is pressed during play, the tonearm will
automatically return to the arm rest, the platter will stop
rotating and play will be suspended (auto cut).
NOTES:
e This switch’s STOP function has no effect on tone-
arm movement unless the tonearm is in contact with
the record.
e This switch cannot be selected when the AUTO
switch ts set to OFF.

SPEED SWITCH
33. .... Set the switch to this position when playing a
33-1/3rpm record such as an LP. When it is
depressed, the 33 indicator lights up, and the
platter rotates at a speed of 33-1/3rpm.
45 ..... Set the switch to this position when playing
a 45rpm record like an EP. When it is de-
pressed, the 45 indicator lights up, and the
platter rotates at a speed of 45rpm.
ARM ELEVATION SWITCH
Use this switch to interrupt play temporarily or to per-
form manual play.
When the DOWN ( ©) indicator lights up, the tonearm
will descend and when the UP ( ¥) indicator lights up,
the tonearm will rise. These two operations will be per-
formed alternately every time the switch is pressed.
NOTES:
e@ When the POWER switch is set to ON, the tonearm
will descend and the DOWN indicator lights up.
Always set the switch to DOWN for auto play.
When the switch is at UP, the auto return cancelling
mechanism is actuated and so there will be no auto
return or auto cut.

PITCH CONTROL KNOB
If this knob is rotated with the Quartz LOCK switch at
OFF, you will be able to increase or decrease the speed of
the platter in respect to its rating. When the knob is
rotated in the ‘‘t’’ direction, the platter will rotate faster,
and when rotated in the ‘‘-” direction, it will rotate
slower than its rating. The PITCH meter can be observed
to check the amount of speed increase or decrease (up to
6% in either case).
QUARTZ LOCK SWITCH
When this switch is pressed, the Quartz PLL
circuitry is actuated and the indicator will
light up. The switch is usually kept at this
position. The platter will be accurately
locked to the rotational speed corresponding
to the position of the SPEED switch.
When this switch is released, the Quartz PLL
circuitry is disengaged, the PITCH meter lights
up and the indicator goes off. Set the switch
to this position for instrumental and other
performances in accordance with the record
OFF. 6:
being played.
PITCH METER
When the Quartz LOCK switch is set to OFF, the PITCH
meter lamp will light up, and the variation in the rota-
tional speed of the platter in respect to its rating (33-1/3
or 45rpm) can be read out on the meter.

RESISTANCE VALUE CODES
Code numbers of resistors used in Pioneer
equipment are expressed in the following way:—
Code number —————----—-> RD % PS 473 J NL
Baose cel
Type of resistor |
Power rating
Shape (tubuler) <
Resistance (code value) <————_____--_
Tolerance <
Low-noise marking ~«<
Furthermore, in the list of parts found in the
Service Manual, the resistance (code value) part of
the above code number is expressed as OU0) or
OOO.
Resistors included in the Service Manual list of

Ex. RD %PSOOO JNL
When ordering resistor components, first ascer-
tain the actual resistance value from the circuit
diagram, and then convert it into code no. form
as shown in the following examples.
