3. ADJUSTING PROCEDURES

3-1. Routine Maintenance

3-1-1. Cleaning

1) Head

With constant use, the head surface becomes soiled with magnetic particles from the tape, dirt and dust. Under such
conditions, the tape will not always be in smooth contact with the head and thus result in poor performance. Less
output in the high region and dropout (some parts of sound not reproduced) are typical symptoms. It is therefore
recommended to clean the heads periodically before recording and playback to avoid such troubles.

2) Capstan and pinch roller

Buildup of magnetic particles and dust on these parts will cause increase in wow, flutter and wrapping of tape on
the capstan. Thus, these parts must always be kept clean. Cleaning is done with cotton buds moistened with fluids
prescribed or recommended for tape recorders and especially the heads. Never use lacquer thinner, acetone or
other organic solvents.

8

3-1-2. Demagnetizing

The REC/PLAY head becomes magnetized by extended use or when the head is touched with a magnetized object.
As a result, frequency response especially in the high region will deteriorate, noise level increases, and in some
cases may transfer noise to valuable prerecorded tapes. For this reason, do not touch the head with magnetized
screwdriver and scissors or allow DC current to flow through the head winding such as when testing continuity
with a circuit tester. Should the head becomes magnetized, demagnetize it with a head demagnetizer designed for
this purpose.

Demagnetizing Procedures

After turning off the power of Model X-34, open the cassette lid and if a cassette tape is loaded, remove and place

1)
it far away from the deck.
Switch on the head demagnetizer while holding it about one meter away from the Model X-34. Then, slowly move

2)
the head demagnetizer tip to the head and wave the tip up and down several times close to the head surface.
On completing the above procedures, slowly draw the demagnetizer away from the head and switch it off when it

3)
is more than one meter away from the head. As demagnetizm in the head cannot be seen, unlike the soiled head,
routine demagnetizing is necessary. It is recommended to do so at the same time the head is cleaned.

3-2. Test Equipment and Adjusting Tools

The following tools and equipment are required for adjusting the Model X-34.

1)

Head height and tape contact adjusting jig Model 9001 (P/N: 8286001000)

3-4. Tape Travel Check and Adjustment

Using the mirror type cassette, check to see that the tape is running stable between the ERASE and REC/PLAY
heads tape guides without weaving. If the tape is not running stable between the guides, erasure and frequency
response will be affected or the tape will be damaged by curling. It then becomes necessary to check the guide
height, perpendicularity of the head surface, and alignment of the pinch roller in relation to the capstan. In addition
to the mirror type cassette, the Head Height and Tape Contact Jig is required. To check the head guide height, the
cassette tape is removed and the above jig is placed on the head mount base plate. While firmly seating the jig on
the base plate surface, slide the jig past each head guide to see that it goes through without hitting them. Also check
perpendicularity of each head surface, using the rear check bar of the jig. If the guide is low, insert the required
amount of 0.1 mm or 0.2 mm thick washers under the head mounting legs, or vice versa, if it is high.

NOTE: Always adjust the head azimuth and phase when the head height is adjusted.

4)
Record the signal, rewind and playback the recorded section of the tape.

5)
Check if the 6 kHz / 12 kHz output level at TAPE OUT 1 ~ 4 is within ± 2 dB comparing to the 400 Hz output level.

6)
If the AC volt meter reading is not within the above specification, adjust the pot R132 ~ 432 (220 kΩ) on the R/P
AMP PCB assy so that the recording level at 6 kHz will be within the specification.

3-14. T.H.D. Measurement

Connect a distortion meter, 400 Hz HPF and 30 kHz LPF to TAPE OUT 1 ~ 4 and set the controls under the same

1)

3-17. Sync crosstalk measurement

Sync crosstalk is a relative figure against the reference level, on how much of the recording signal from a track in
recording mode is leaking into the track being reproduced. When sync crosstalk is excessively high, playback output
during overdubbing will sound muddy by effect of the recording signal leakage or cause oscillation at pingpong
recording (where the playback output is transferred to another track).

Set the controls as follow and put a blank tape to the transport.

1)
Trim knob: At minimum
Input fader: Standard position (At 8 ± 1)
Dolby B noise reduction on/off switch: OFF

Apply a signal whose level is -10 dBV (0.3 V).

2)

Put one track into REC mode and check if the level at TAPE OUT on an adjacent track is within the specifications

3)

listed below when sweeping the oscillator frequency.

At 1 kHz: -25 dBV or less
1 ~ 20 kHz: -10 dBV or less
