It is possible to select either normal tape speed or high tape
speed when you perform dubbing from the deck
to the deck
2 and the high speed is twice as fast as the normal speed.
l
Normal speed/high speed record selector circuit
Being provided at the deck 2, the integrated circuit works to select the normal speed mode or the high speed mode: the frequency at the high speed is two times higher than that at the normal speed. The
also works to detect whether a normal tape or a metal tape has been loaded in the unit.
l
Normal speed/high speed playback selector circuit
Being provided at the deck 1, the integrated circuit works to select the normal speed mode or the high speed mode: the frequency at the high speed is two times higher than that at the normal speed. Here is also given proper equalization for the signals of both speed modes. Further the
changes its constant according to whether a normal tape
or a metal tape has been loaded in the unit.
l
Normal speed/high speed selector circuit
Change of the motor’s rotational speed results in a changeover between the tape normal speed and high speed modes. The electronic switch is used to act on the motor control circuits of the deck 1 and deck 2 at a time as their speeds are
Fig. 6-2 shows how the circuit works to get the unit in the high speed mode, whose expression is made with use of the mechanical switch instead of the electronic switch.
(Automatic Program Pause System)
The existing APSS, as you know, is to automatically detect an end of the program when the unit is in fast forward or rewind mode and then to return it to play mode. The APPS employed for the GF-SOOH/E is something new which is based on the same ideas as with such APSS, and it is activated not only when the unit is in play mode (at the deck
only) but also
when it is in dubbing mode (from the deck 1 to the deck 2).
In the dubbing mode (either at normal speed or at high speed), as soon as an end of the program is detected by the APSS in the deck 1, the APPS works to stop the motor circuits of both decks 1 and 2 simultaneously -that is, motions of the deck 1 and deck 2 are stopped just at a time. Therefore, the deck
has two automatic controls
APSS and APPS, that is, it is controlled by the APSS when it is in play mode (with the deck 2 in stop mode) and by the APPS when it is in dubbing mode. The two controls APSS and APPS are differentiated by the following:
l
Difference in gain and frequency characteristic between
APSS and APPS.
l
Difference in program detect time between APSS and
APPS.
These differences are due to that the tape speed is different
according to whether the unit is in play mode or dubbing
mode, and according to these, the electronic switch selects the
APSS or APPS to get it in action.

PINCH ROLLER PRESSURE CHECK
1. Place the unit in PLAY mode.
2. Push the pinch roller, at the point shown in Fig. 9-1, by using a tension gauge (500
so that it will come off the capstan. Then, release the tension slowly until the pinch roller hits the capstan again (i.e., the pinch roller is about to rotate again). Then check the tension gauge is reading 350 gr. to 420 gr.
3. If the reading is outside the range of 350 gr. to 420 gr. replace the pressure spring of the pinch roller.
TORQUE CHECK AT PLAY, FAST FORWARD AND
REWIND MODES
Put a torque meter cassette in the cassette compartment of the
set, and see that the measured torque in each mode is normal
as follows:

Note:
The high speed operation has priority over the normal speed
operation, and so try to do the adjustment for the former first
and then for the latter.

the deck 2.
For Normal Speed Operation:
1. Play a test tape (TEAC,
prerecorded).
2. Adjust the semi-variable resistors (VR503 for the deck 1 and VR504 for the deck 2) located on the deck 1 and deck 2 mechanism P.W. Boards, so that the output frequency is 2985 to
on the wow/flutter meter for both decks 1
and 2.
RECORD/PLAYBACK HEAD AZIMUTH ADJUSTMENT
1. Make Connection of instruments as shown in Fig. 9-4.
2. Set the Dubbing switch SW201 to the off position and Tape Selector switch SW105 to Normal position.
3. Adjust the head azimuth adjusting screw so that sine waveform attains the maximum and the same phase in right and left.
4. Even without using the oscilloscope, also adjust the head
azimuth adjusting screw so that outputs of both the right and left channels attain the maximum and the same phase in right and left.
Note:
For some heads, there may be a phase difference between
right and left channels when the output is made maximum.
In this case, adjust the head azimuth so that such phase difference will be as small as possible while keeping the output still maximum.
