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 .

really a very good manual even sometimes the quality is no so good as before still very readible and very very useful!
TUNER SECTION
0 dB=1µV
AM Tuning Voltage Adjustment
DC voltmeter
Main board TP1 G VT
+ �
Procedure: 1. Set the reception frequency of the unit to 530 kHz. 2. Adjust L105 for 1.2 ± 0.05 V reading on the DC voltmeter. 3. Set the reception frequency of the unit to 1,710 kHz. 4. Confirm that the voltage reading on the DC voltmeter is within 8.0 ± 0.5 V. Adjustment Location: MAIN board (See page 14)
AM Tracking Adjustment
loop antenna loop antenna (Supplied accessories)
AM RF SSG set 30% amplitude modulation by 400 Hz signal AM ANTENNA terminal (TM1)
60 cm
Field strength dB (µV/m) =SSG output level dB (µV/m) �26 dB.
Procedure: 1. Tune the set to 600 kHz. 2. Set the output of AM RF SSG so that the input level of the set will become 60 dB (µV/m). 3. Adjust L104 so that when the waveform on the oscilloscope is maximum, no noise appears. 4. Tune the set to 1,400 kHz.
5.
Adjust TC102 so that when the waveform on the oscilloscope is maximum, no noise appears.
� Repeat the procedures in each adjustment several times, and the tracking adjustment should be finally done by the trimmer capacitors. Adjustment Location: MAIN board (See page 14)
