Doubted for buy this manual as it is my first order here and at not have cover image, I assumed would haven't. However, within 24 hs, already possessed the link to download it. The manual are scanned correctly and have all what is needed. Includes adjustments and diagrams of all circuits. Very satisfied.

MTS ADJUSTMENT
(Only for 25L-S100/180, CL25S18)
MTS Level Adjustment
1. Feed the following monaural signal to pin (14) of IC3001. Monaural signal : 300Hz, 245mVrms 2. Connect the rms voltmeter to pin (39) of IC3001. 3. Enter the service mode and select the service adjustment "M01". 4. Adjust the data so that the rms voltmeter reads. 490 ±10mVrms.
MTS VCO Adjustment
1. Keep the unit in no-signal state. 2. Connect the frequency counter to pin (39) of IC3001. 3. Connect a capacitor (100µF, 50V) in between positive(+) side of C3005 and ground. 4. Enter the service mode and select the service adjustment "M02" 5. Adjust the data so that the frequency counter reads. 62.94 ±0.75kHz.
Filter Adjustment
1. Feed the following stereo pilot signal to pin (14) of IC3001 . Stereo pilot signal: 9.4kHz, 600mVrms. 2. Enter the service mode and select the service adjustment "M03". 3. Adjust the data at the point where "OK" appears on the screen. The "OK" represents the approximate center of the adjustable range of the data.
Separation Adjustment
1. Connect the rms voltmeter to pin (39) of IC3001. 2. Receive the following composite stereo signal 1. Composite stereo signal: 30% modulation, left channel only, noise reduction on, 300Hz 3. Enter the service mode and select the service adjustment "M04". 4. Adjust the data until the AC voltage reading of the rms voltmeter is minimum. 5. Receive the following composite stereo signal 2. Stereo signal: 30% modulation, left channel only, noise reduction on, 3kHz 6. Enter the service mode and select the service adjustment "M05". 7. Adjust the data until the AC voltage reading of the rms voltmeter is minimum. 8. Take the above steps 1 thru 8 again for fine adjustment.
