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,

Maintenance of laser pickup
(1) Cleaning the pick up lens Befor you replace the pick up, please try to clean the lens with a alcohol soaked cotton swab. (2) Life of the laser diode (Fig.1) When the life of the laser diode has expired, the following symptoms wil appear. (1) The level of RF output (EFM output:ampli tude of eye pattern) will below.
Replacement of laser pickup
Turn off the power switch and,disconnect the power cord from the ac outlet.
Replace the pickup with a normal one.(Refer to "Pickup Removal" on the previous page)
Is RF output 1.1 0.15Vp-p?
NO
Replace it.
Plug the power cord in,and turn the power on. At this time,check that the laser emits for about 3seconds and the objective lens moves up and down. Note: Do not observe the laser beam directly.
YES O.K (Fig.1) Check the eye-pattern at TP1. Play a disc.
(3) Semi-fixed resistor on the APC PC board The semi-fixed resistor on the APC printed circuit board which is attached to the pickup is used to adjust the laser power.Since this adjustment should be performed to match the characteristics of the whole optical block, do not touch the semi-fixed resistor. If the laser power is lower than the specified value,the laser diode is almost worn out, and the laser pickup should be replaced. If the semi-fixed resistor is adjusted while the pickup is functioning normally,the laser pickup may be damaged due to excessive current.
Finish.
