PLAY motor (M103)
* Adjustment location : SIFR101(PCB-C)
Method : Play the approximately middle section of
the test tape and adjust SFR101 so the voltage
at the test point is 3.0+0.1V.
. Tape Speed Adjustment
Settings : + Test tape : TTA-100(TTA-111S)
* Test point : LINE OUT jack
+ Adjustment location : SFR in capstan motor

(1.5kHz) Method : Apply a lkHz signal and adjust the attenuator
so the output level at the LINE OUT jack is

signals and adjust so the output difference
of both signals is +0.5+0.5dB.
* Test point : LINE OUT jack

Method : Record a 125Hz signal of +10VU on test
tape TTA-620(TTA-119MP) using this unit.
Rewind the recorded section and set to the
erase state. Turn the hexagonal nut gradually
clockwise and check that 125Hz vaveform
appears in the Rch playback output. Then turn
the hexagonal nut counterclock-wise and stop * Adjustment locations :
it where the output is minimum, then turn it
by a half turn more counterclockwise.
(Over-erase check]
Play test tape TTA-150(TTA-111H) and assume
the Rch output as a reference output. Then
turn over TTA-150(TTA-111H) and set to the
erase state. Turn over the tape again and play
the reverse side of the erased section and
with the reference output is within 1dB.
