About the service it's very fast and reliable. About the manual the quality is high enough to read even the tiniest details on the wiring diagrams so you can't ask much more than that, let it alone for a manual of a product from 20 years ago. Thank you, very satisfied.

6. IF Adjustment (MW) Requirement Measuring equipment: Oscilloscope or Millivoltmeter Test point: TP8(Lch), TP9(Rch), GND Adjustment point: L802 1) Adjust the setting of Standard Signal Generator (hereinafter S.S.G.) to 999KHz of 30% variation. 2) Adjust the receiving frequency of the main unit at 999KHz. 3) While looking at the waveform on the oscilloscope, reduce the output level all the way (till a certain degree of is monitored through the oscilloscope). 4) Adjust L802 until the waveform of the oscilloscope reaches the maximum. 7. Tracking Adjustment (MW) Requirement Measuring equipment: Millivoltmeter Test point: TP8(Lch), TP9(Rch), GND Adjustment point: L952, L953 1) Adjust the S.S.G. setting to 999KHz of 30% variation and reduce the output level all the way (till a certain degree of is monitored through the oscilloscope). 2) Adjust the reception frequency of the main unit to 999KHz. 3) Adjust L952 until the value of the millivoltmeter reaches the maximum. 4) Adjust the S.S.G. setting to 603KHz of 30% variation and reduce the output level all the way (till a certain degree of is monitored through the oscilloscope). 5) Adjust the reception frequency of the main unit to 603KHz. 6) Adjust L953 until the value of the milivoltmeter reaches the maximum. 7) Repeat the adjustment 2 or 3 times from step 1 to 6 above.
