again you did a very good job. It was fast too. Photocopy are really readable and clear
 ;
Probably it never existed a 1081 official service manual from Commodore, it's look more like a NAPCEC service manual & diagrams compilation of the 1084 series and his variants, like the nap6523, 8cm505, 1084S, 1084P and obviously the 1081. It's more complete than other scans and the quality of the scans also are far superior. It has two circuit diagrams variants of the 1081, mono and stereo versions. It doesn't include a diagram for the Philips CM8500 or CM8501, they look like the 1081 but they are slightly different.

Rapid, clear well done as all the scheme I downloaded from this site. Great job very functional and very useful
;
Great copy of the manual, has all information required for servicing,

I work at an authorized service center and I can tell if a manual is as it should be. This one is. It may be a scan, but a very good one at that. The interesting part for me was the curcuit diagram which was scanned at high quality, making it as good as the original. I will definitely be back as a customer. I need not say this, but I will: the price was the best. Thank you owner-manuals.com .
ELECTRICAL ADJUSTMENT -2/5
5. DC Balance Check Requirement Measuring equipment: Digital multi-meter Test point: TP2, 3 1) Adjust the reception frequency of the main unit to 98.0MHz. 2) Check that the test point voltage difference between TP4 and TP5 is 0mV±500mV.

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.
