Thank You for fast delivery for the sheme.
Everything allright.
Thanks & best regards Franz

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,
ELECTRICAL ADJUSTMENTS

Notch
1. Connect the AC voltmeter to pin 6 of CP101. 2. Activate the adjustment mode display of Fig. 1-1 and press the channel button (35) on the remote control to select �LEVEL�. 3. Press the VOL. UP/DOWN button on the remote control until the AC voltmeter is 85 ± 2mV. 2-12: SEPARATION 1, 2 (RF, AV) Please do the method (1) or method (2) adjustment. Method (1) 1. Set the multi-sound signal generator for each different Lch and R-ch frequency (Ex. L-ch=400Hz, R-ch=2KHz) and receive the RF. 2. Connect the oscilloscope to the Audio Out Jack. 3. Activate the adjustment mode display of Fig. 1-1 and press the channel button (36) on the remote control to select �SEPARATION1�. 4. Press the VOL. UP/DOWN button on the remote control to adjust it until the audio output wave becomes a fine sine wave. 5. Press the CH UP button once the set to �SEPARATION2� mode. Then perform the above adjustment 4. Method (2) 1. Set the multi-sound signal generator L-ch=1KHz, R-ch =Non input and receive the RF. 2. Connect the oscilloscope to the Audio Out Jack (R-ch). 3. Press the AUDIO SELECT button on the remote control to set to the stereo mode. 4. Activate the adjustment mode display of Fig. 1-1 and press the channel button (36) on the remote control to select �SEPARATION1�. 5. Press the VOL. UP/DOWN button on the remote control to adjust it until the R-ch output becomes minimum. 6. Set the multi-sound signal generator L-ch=Non input, R-ch=1KHz and receive the RF. 7. Connect the oscilloscope to the Audio Out Jack (L-ch). 8. Activate the adjustment mode display of Fig. 1-1 and press the channel button (37) on the remote control to select �SEPARATION2�. 9. Press the VOL. UP/DOWN button on the remote control to adjust it until the L-ch output becomes minimum. The output difference of the between with Filter and without Filter should be more than 25db for both L and R.
Shadow mask Fig. 2-1
2-7: VERTICAL SIZE (RF) 1. Receive the cross hatch signal from the Pattern Generator. 2. Using the remote control, set the brightness and contrast to normal position. 3.
