Pulley 50 Hz, Part No. 261 938 / 60 Hz, Part No, 261 939
Locking rail 50 Hz Part No. 261 916 / 60 Hz Part No. 264 027
Conversion to the given line voltage should be carried out in accordance
with the connection diagram.
Speed changeover
The speed switch lever is brought into the required position (33 or
45 rpm) by means of the speed lever 18, the switch lever and the
spring lever of the switch levers. If the machine is switched off, then
the switch lever is interlocked ty the locking rail 9. The speed is only
pre-selected in this way. The locking rail 9 is only released when the
platter 5 turns. This then moves the flat belt 15 onto the required
steop of the motor pulley 116.
Platter
The platter is secured to the securing disc 1 by the bayonet catch.
When removing the platter 5 press the securing disc lightly downwards
and turn it approximately 60° to the right until it is felt to click out of
position.
Flat belt
As described above, the platter must be removed in order to change the
flat belt 15. Remove the old flat belt. Place the new flat belt onto the
running surface of the flywheel rotor 30
Changing the drive pulley
1. Remove the flat belt 15 and the toothed beit 109.
2. Detach tension spring 115 from motor plate 125.
3. Remove the hex nut 111, the adjustment cam 112 the belt pulley
113 and the counter bearing 114.
4. Loosen grub screws and remove motor pulley 116. Place the replace-
ment motor pulley on the motor axle. Remove the taper bush. Take
care with the interior spacing bush. Adjust the motor pulley vertically
(see fig. 1 ) and tighten the grub screws uniformly. Place the taper
bush in the motor pulley 116.
5. Counter bearing 114, belt pulley 1 113 and adjustment cam 112 should
now be fitted and the hex nut 111 should now be tightened. Replace
the tension spring 115 and the toothed belt 109.
Fit the flat belt 15 onto the motor pulley.
6. Set the belt pulley 113 to itscentral position by turning the regulating
knob 16, (The lug of the belt pulley should be evident in the middle
of the drive pulley). Set the rated speed by means of the hex nut
Hu
The rated speed may be increased by turning the hex nut 111 in a
clockwise direction. The rated speed may be decreased by turning
the screw in an anti-clockwise direction,
Pitch control
By turning the fine speed regulating knob 16 the belt pulley 2 105 can
be moved. This rotation is transferred by means of the toothed belt 109
to the belt pulley 1, thus moving the counter bearing 114 and the taper
bush of the drive pulley 116 upwards or downwards. The taper bush of
the drive pulley 116 is designed to vary the diameter of the drive pulley
thus varying the nominal speed within the tolerance of +3 %.
Tone arm with Bearings
To Remove the Tone arm Complete with Bearings
1. Adjust the rotary knob 54 to zero, Lock the tone arm 40 in place.
Remove the weight 41.
2. Remove the screening plate 158. Unsolder the tone arm leads from
connection plate 156,
3. Unhook the tension spring 226 from the bearing stay 224. Re-
move the bearing part 195. Detach the adjusting rail 194.
Unhook the tension spring 214.
5. Remove lock washer 217 and the sliding washer 216, Detach the
switch off bar 215 from the segment 211
6. Slacken the hex nuts 213 and the screw 205. Remove the counter
bearing 204 and the segment 211
>
7. Grip the Frame 47 and the tonearm 40. Loosen the machine screw
48 and take off the tonearm and frame.
To install the tone arm, proceed
in reverse sequence; however, make
sure the segment 211 is properly adjusted as described.
To Remove the tonearm or the spring housing
1. Turn the rotary knob 54 to the zero position. Lock the tonearm
40. Remove the weight 41.
2. Remove the screening plate 158 and solder off the tonearm con-
nections at the connection plate 156.
3. Remove the screw 56. Remove the rotary knob 54 and the washer
53.
4. Loosen the nut 50 and the grub screw 51. Draw the tonearm 40
complete with bearing 57 from the bearing frame 52. The spring
housing 58 or the tonearm 40 may now be changed,
Reassembly involves the reverse procedure.
To Adjust the Tone arm Bearings
Exactly balance the tone arm. Both bearings should have a small, just
perceptible backlash. Proper adjustment of the horizontal bearing is
achieved if the tone arm can freely slide from the record inside to out-
side while the anti-skating adjustment is 0.5. Proper adjustment of the
vertical bearing is achieved when the carefully kicked tone arm swings
into balanced position,
Adjust the backlash by grub screws 46/51 for the horizontal and
vertical bearing, respectively.
Tone Arm
To Replace the Lift Plate
1. Detach the tension spring 226 from the bearing stay 224, Rotate
bearing part 195 through 90° degrees and remove it. Remove the
setting rail 194.
Detach the tension spring 214,
Remove lock washer 217 and sliding washer 216. Detach switch-off
bar 215 from segment 211.
To replace the lift plate 182, proveed-in reversed sequence, but look for
proper Adjustments (described below) when you fix the segment 211.

Starting and Shutting Off
Swinging-in of the tone arm 40 causes rotation of segment 211. As a
result, paw! 186 and switch arm 142 will operate the switch 152 causing
the motor 131 and turntable 5 to rotate.
After the record has been played, the dog M of the turntable will
operate the shut-off lever. During play-back, the switch-off bar 215 is
dragged in proportion to the motion of segment 211. For records 116
to 122 mm in diameter, the shut-off lever is gradually pushed to. dog M
by the switch-off bar 215 in the shut-off range. When the dog M con-
tacts the shut-off lever A, the carrier 94 will move the shift arm 142
to its zero position and the power switch will interrupt the supply.
At the same time the lifting rail 218 coupled to the switch arm 142 will
operate the tone arm lift and the tone arm 40 will be lifted.
Adjustments
1. Segment
a) Lock the tone arm 40 in place. Moreover, a play of 0.3 to 0.5 mm
should be provided between the pawl 186 and the stop A of segment
211, adjustable by slackening the hex, nuts 213 and shifting the
segment 211
b) The excenter S on segment 211 can be used to vary the shutoff
point for records 116 to 122 mm in diameter.
2. Pawl
With the excentric bolt adjust the switch-way of the lever 142.
To adjust the switch-way so that
a) the power switch must be switched safety
b) the segment 211 comes free from the pawl 186.
3. Tonearm lift
Slightly rotate the adjusting sleeve 181. The stylus should be lifted
from record by 3 — 5 mm
