II. Explanation concerning the separately supplied parts.
Center pen: This pen (63) is used for automatic play. [SPINDLE]
Short playpen: When single discs have to be listened to, which can not be played automatically
abnormal sizes, for example) the center pin can be replaced with this short playpen. The device is now
not operated automatically, but manually.
These 4 springs are used to suspend the disc changer elastically, the screws are
screwed into the housing, while the changer discs is attached to the intermedian
plate. By means of the separate fixing screws.
P.U.Unit:
These units delivered in tropical packaging must be attached to the pick-up arm. (See also Chapter I).
Note: Do not forget before commissioning it

IV. Connection and electrical data.
The mains cable must be connected to the two bottom connection points on the motor switch plate
(fig.1).
From both figures A and B (fig.1). it is easy to see how switching from 110 to 220V and vice versa
can be performed.
To connect to a different mains frequency 60/50/40hz, it is necessary to fit a different pulley (1) on the
shaft of the motor. NO LONGER AVAILABLE [I had mine reduced/machined locally in 3 20% steps for
60hz operation]
These pulleys are included in the parts list, stating the mains frequency for which they are intended.
When another pulley is applied, the number of turns of the plate must be adjusted
again, as indicated in IX-8. USE A STROBE
Connection of the P.U. unit takes place in the sealed junction box, which is mounted below the
mounting plate. The shielding of the P.U. cable is connected to the middle soldering lip (fig.2). Parallel to
the P.U. terminal, a resistor (R1 - FIG. 2) of 0.47 M ohm is connected for good adjustment of the
crystal P.U. unit.
[I added a MONO-RCA plug/jack pigtail.]
9

The pickup cord ends in a shielded connection box. To connect it to a radio receiver or an amplifier it is
necessary to make use of a shielded cord of weak[small] capacity with 2 conductors. The shield is
connected to the central lug (Fig. 2). To improve the reproduction characteristic, a parallel resistor on
the pick-up was mounted in the connection box. Resistance of: 0.47 M Ohms adaptation (R1 Fig. 2). i.e.
470k ohm

V. General properties and operation [(see fig. 3)
GENERAL CHARACTERISTICS AND CONTROL
After the center pin is placed in the center hole of the turn table (65) (shoulder in the direction of the
base of the plate press (62) -) and the pick-up unit is pushed onto the P.U. arm, the device is ready for
use.
Since this changer is suitable for playing normal, as well as micro-groove discs and is more over suitable
for different speeds and disc diameters, the positions of the operating elements will first be explained
with the aid of FIG. 3
Speed lever A:
The speed of the turntable is adjusted by setting the speed lever in the relevant position, At 78, 45 and
33 1/3 rpm. Move the trade while the motor is running. This is to prevent the rubber surface of the
intermediate wheel (43) from undergoing a DEFORMATION..
Diameter BUTTON B:
11

When the button is in position 10 "-12" (25-30cm), the changer is suitable for playing discs of those
diameters.
Plays with this diameter can be played in position 7 "(17.5 cm)
Control KNOB C: This allows the machine to be started and stopped.
REJECT>>START>>> STOP >>> FWD >>>
1.Element/ Socket with double needle (AG3005). By the unit
The "M" can be placed in front of the stripe on the arm, in which case the unit is set for playing
micro-grove discs, if the pick-up head is turned to N, then plates with normal groove can be used.
2. Sensor head with single needle. This head can be compared to
the pick-up arm only occupy one position. Here it depends on the type used, which discs can be played
with this (see overview of sensor heads under Chapter I).
PALPE/Taster/feeler/probe E:
[ ... ’E ‘ remains LATCHED until a disc/record is ready to drop [“CHANGE”...]
When a 30 cm plate is placed on the turntable from the shoulder of the center pin, the
palp/probe/feeler /taster is pushed backwards [the taster finger near the control disc teeth pivots
upwards towards the P U ARM]. As a result, the mechanism for the horizontal movement of the sensor
is controlled, so that the needle
in the inlet/first groove of this plate.
The plate printer/platendrukker item 62 fig 8 F:
This part performs two functions, namely
1. Keep the plates horizontal, which is at the center pin,
2. To automatically switch off the disc changer at the ending of the last record.
From the above it appears that the position of A, B and D depends on the plates to be played, so that
this must be taken into account. [where is D ?..there is a D on fig 8
p5a
After the plates to be played have been placed on the shoulder of the center pin and the plate press has
been pushed over the center pin, the record changer is ready for use.
12

When the appliance is switched off, after the last plate has finished, the plates can be removed after
removing the plate press[62] and the center pin.
REPEAT KNOB R.
By pressing this button a played record can be repeated.
Note regarding the dimensions of the gramophone records.
As is known, in this type of changer the thickness of the disc must meet certain requirements. The
thickness must be between 1.7 and 2.5 mm, measured in the center hole. The diameter of the center
hole is approx. 7 to 7.5 mm. The exchanger is set so that the normally occurring discs can be used, also
with regard to the outside diameters. Manual operation must be applied for abnormal plates.

1. This disc changer plays up to 10 RECORDS together
of 25 and 30 cm (10 "and 12"). The stacking here may be arbitrary. In addition, 10 plates of 17.5 cm (7 ")
can be played.The entire process is started by putting the control knob  (C fig.3) >>forward>> (start),
after which the knob automatically returns to the rest position after this again is released.

3. By placing the control knob in the "stop" position, the
the changer is automatically switched off  after the ending of the currently playing record.
4. By pulling/PLACING the control knob forward at a moment when a plate is being played, the
mechanism comes into operation; the plate is interrupted and replaced by the next record, which is
played again from the beginning (reject).
5. By pulling/placing the control knob >>forwards at a moment when a plate is being played and then
placing/positioning the knob into the stop position, the changer is immediately stopped.
P5b
6.  Each 25 cm and 17.5 cm disc can be repeated. When
rehearsing 30 cm discs, the pickup fits well on the disc, but
2.5 cm inwards. For repeating a disc, the Repeat button must be
pressed during playback of the disc in question. One can also
repeat a partially reproduced disc. For this you must first
press the repeat button and then start, the repeat button
returns
automatically to its old position.
7. With the help of the supplied short pin, the plate wiping [ my short pin is missing]
be used as A TURNTABLE with automatic switch-off after the end of the record. While the control knob
is in the rest position, the arm (95) is brought onto the plate by hand. After this the button must be
placed in the "stop" position. The RECORD PLAYER is turned aside
8. Continuously repeating a 25 cm (10 ") and a 17.5 cm (7")
DISC is possible in the following way:
Raise the plate presses/platendrukker and turn them aside. The control button must remain in the rest
position after starting and the DISC will be repeated continuously, without using the repeat button.
14

P6a
9. The pick-up arm may always be moved manually when it is once on the plate, for example to repeat a
particular passage. Do not touch the arm when it is moved automatically!
10. When the mechanism comes into operation (either by 'start’ or ' reject 'or at the end of the
DISC) then there is always a next disc.. If you want to hear the same record/disc again after  3
and 5,[ 3. By moving the control knob to the "off" position, the
unit is in the OFF stopped at the end of the drive. ... 5. By pulling the control button forward
while a disc is moving and then returning the button to its stop position, the disc changer stops
immediately.]
 The repeat button must be used. In addition, the repeat button can be prevented from being skipped
when the operation is carried out under maneuvers 3 on 5[see above] and then restarted.
11. The disc changer  is fool-proof on the understanding that extra attention must be paid to the
position of the P.U.unit in connection with the type of grove of the disc.

See also p35..The speeds 78 and 33 1/3 are fixed by the cams (50). For the speed 45 this is effected by
the leaf spring (51). The positions 33 1/3 and 78 revolutions per minute are pressed against the relevant
cams by the horseshoe spring (54). The turntable and the hearing axis are connected to each other.
When the turntable turns, it also turns on this main axis. These are the only ones turning during the
playing of a record
parts that are in motion (apart from the movements of the pick-up arm). The teeth of the main shaft
[main shaft of the platen ]rotate along the toothless portion of the command dial/control disc (124).
The motor by turning the platform/platen (65) by the intermediate wheel (43), this
intermediate wheel can be moved by the speed knob (A Fig. 3) along the axis of the
motor. 33-1/3 are fixed by the cams (50) The positions 33 1/3 and 78 are obtained by
the horseshoe spring (54) pressing the lever against the stop The intermediate
position (45 revol / min) is blocked the spring plate (51) The plateau and main axis
are united.When the plate rotates, this main axis also rotates.When playing a disc
these are the only pieces that are in motion (except for the movements of the arm The
teeth of the main axis rotate along the ie not toothed from the control disk (124)
P6b...
1. START-UP
There are 2 ways to close the start switch;
First [SEE ALSO 8.] by lifting the P U Arm hand-operated manually) and
secondly by using the start lever.. When the P.U. arm raises during automatic play, the switch
remains closed, however, the spring system rises in its entirety to enable subsequent switch-off by the
P.U. arm. REJECT....START...STOP >FWD
16

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
However, when the control knob is pulled forward,TO ‘START’ the LONG curved starter spring (FIG .6
23) is also moved, which in turn touches the floppy driver (FIG 9 127) on the CONTROL DISC . The nose
of the floppy driver[127] touches the cam D (fig.8) under the platen teeth on the main shaft, which gives
the CONTROL disc an impulse. This impulse is just sufficient to cause the teeth of the main shaft to grip
in the teeth of the control disc , as a result of which it starts to rotate. It may happen that the MOTOR is
switched on when the MOTOR is started, after which the CONTROL DISC will remain standing. In this
case one has switched too quickly and the taker jumps back without being hit by the cam on the main
shaft. In this case, one will have to go again
There are two ways to close the start switch; first by lifting
the pick-up arm by hand (hand-operated and secondly by using the
starter lever.When in case of automatic operation the pick-up
arm raises, the switch remains closed, but the spring-loaded
system is lifted all the way up so that the pickup arm can be
switched off, but when the CONTROL KNOB is pulled/PUSHED
forward, the starter spring is also actuated (FIG 6 23) and In
turn, the spring drives the drive device (fig 9 127) onto the
disk as the nose of the drive device [127] contacts the cam (D
Fig. 8) of the main axis, which gives the drive a pulse. This
impulse is just enough to make the teeth of the main exe
bite into those of the control disc which then starts to
spin.It may happen that when starting the motor is well engaged,
but that the drive disc remains immobile, which means that we
have operated too quickly the drive device returns without
having been touched by a cam of the main axis. In this case it
is necessary to restart the start. The control disc is the heart
of the disc changer: it controls all movements and a single
rotation.
The CONTROL disc is the heart of the changer, so that all movements are controlled in one revolution.
P7a
2. The Mechanism.
The best way can be followed by turning the turntable by hand in the correct direction (i.e. to the
right). VIEWED FROM THE TOP [TO THE LEFT ..CCW... IF UPSIDE DOWN] The plate
press/platendrukker [62] is turned to the side and the P.U. arm is on the support. There are no DISCS
17

on the SPINDLE/center pin and the stacker unit has been removed. After the control disc / command dial
is linked to the main axis, it will also rotate when the turntable/ platter is turned.
.
3. Vertical movements of the P.U.arm
Under the influence of the large long  CHUBBY tension spring (81) the lever tonge/ upper lifting strip (B
fig.8) is pulled in the >>>direction of the axis >>> of the control disc /command dial and rests against the
roller (123) on the cam disc. As When the control disc /command dial rotates, the roller rotates away
from the lever tab/ lifting strip, causing it to move >>>towards >>> the axis. As a result, the pick-up will
be pushed upwards by the lifting disc [82] . The movement/stroke is limited by the pin on the bottom
plate (73).
When at the  end of the revolution  of the control disc
When the roller 123 touches the lever plate/ lifting strip again, it is pushed back again, now in the
opposite direction against the force of the spring, and this gives the P.U, again the opportunity to fall
back descend, hereby helped by the pressure spring (85) under the pick up arm . The vertical
movements of the P.U.arm have now become clear. In order to prevent arbitrary/ random movements
of the P.U. arm when it is lifted off the, the disc ,the lever plate (H fig. 8) UNDER THE PRESSURE
SPRING 85 rests on a plastic disc which is mounted on the lifting disc.
4. The changer mechanism.
Under the influence of the SMALL skinny LONG tension spring (75)the change device/ insert LOWER
PLATE (74) is also pulled towards the control disc/command dial. The roller (68) on the changer presses
against the cam disc.
When the control disk rotates, there is a moment when the wheel/roller follows the profiled portion
of the disk, causing the change device to move in the direction of the command disk axis and then be
pushed back again. As a result of these movements the hinged part of the center pin is moved back and
forth.
P7b
5. Operation of the spindle / Center Pen.
As soon as the hinged part of the center pin (63) is moved by the changer device, all the discs are pushed
aside from the bottom side. The shoulder of the hinged pin, on which originally all the plates rested,
now fits in the extension of the pin, giving the bottom disc the opportunity to fall. The others rests on
the fixed part of the center pin. When the hinged part of the pin is pushed back by the mechanism, the
18

discs fall onto the shaver of the pin, with which they are thus returned to the original position. The
mechanism is suspended with leaf springs to absorb the shock of the falling package of discs.
6. >>>>>>>>>>Horizontal movements of the P.U.arm for [10” and 12”] 25 cm and 30 cm discs.
The high axle on which the P.U.arm is attached forms a whole with the steering hook (fig 9. 111). The
hori. zonal movements of the hook are made and therefore also by the P.U.arm. In the control disc
there is a component combination, (which will be called in the next "roll"), which can slide back and
forth in a radially oriented slot (fig 9. 130 - 137). The fork-shaped steering hook is hit by this roller when
the control disc is running. For example, the steering hook (and thus the P.U.arm) is moved in after a
disc has fallen. If the P U arm is lowered again, the needle must end up on the edge of a 25 cm (10 ")
plate, the turning of the steering hook will take place in the same way, on the understanding that the
roller (137) against the other leg of the fork, for 30 cm (12 ") plates the process is carried out in the same
way, only in the following way
the P.U.arm is turned in too much. When a 30 cm (12 ") plate falls, it touches the probe (E fig.3).
Because it is retracted, the steering hook is blocked so that the needle lands on the beginning of a 30
cm plate. the control disc now slides in through the radial slot, and is led out again through the
crescent-shaped plate (A fig.9).
The palp/ is brought back to the 10”/25 cm position by the fin/LEAF (A, fig.6).
6. Horizontal movements of the pick-up arm for 25 and 30cm discs
The hollow shaft on which the pick-up arm is fixed forms a whole with the guide hook
(111 fig 9.) The horizontal movements of the hook are also followed by the pick-up
arm. In the control disk is a set of spare parts (130-137) (which will be named "roll"
in the following), which can slide back and forth in a groove directed radially, the
hook of fork guidance is achieved by this roller when the control disk rotates. The
guide hook (and consequently the pick-up arm) then move inwards when a disc has
fallen. If the pick-up arm falls down again, the needle should coincide with the edge
of a 10”/25 cm disc.
The rotation of the guide hook to the outside is analogous, it being understood that
the roller (137) now presses against the other branch of the fork. For 30 cm discs the
process is the same, with this difference being avoided in the following way that the
pick-up arm is placed too much inside. When a 30 cm disc falls, it touches the palp
(E fig 9).[don’t see E FIG 9 ][PALPE..TOUCHER/FEELER/PROBE ? ]
As it is pushed back, the guide hook is blocked, so that the needle is at the
beginning of a 30 cm disc. The roll of the control disk then moves. towards the inside
in the radial groove, but is then guided outward again by the half-moon plate (A,
Fig. 9). The palp is brought back to the 25 cm position by the fin (A, fig.6

7. Horizontal movement of the P.U.arm for 7” = 17.5 cm discs [45rpm]
As already known, we must play for gramo. phonographs with a diameter of 7 "the diameter slide in

This will now also take the small guide/ steering hook (112) [this ASSOCIATED plate has the

will now start from the moment the P U arm is moved from the inside out, which takes place in the
normal way already described. The control disc rotates at a constant speed and now touches the small
steering hook, which rotates around its axis.The steel wire spring (FIG 9 113) attached to the end of this
steering hook touches a pin on the GUIDE/steering hook (B fig.9). this starts to rotate, which causes
the handlebar and therefore also the PU arm to move further in. This difference in rotation is
determined by the distance (X). (fig.9) The roller turns tade small handlebar from the inside to the
outside and leaves at a given moment the small steering hook, which shoots back under the influence of
the torsion spring (FIG 9 117) and bumps against the diameter shifter, but now also the large steering
hook is no longer swiveled and the PU is
just above the beginning of a 7 "plate, because the distance of the P.U. is greater than that of 25 cm
(10") plates and the times used are almost the same, the speed for both
