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 .
4.7.8 PURITY AND CONVERGENCE PURITY ADJUSTMENT (1) Demagnetize CRT with the demagnetizer. (2) Loosen the retainer screw of the deflection yoke. (3) Remove the wedges. (4) Input a green raster signal from the signal generator, and turn the screen to green raster. (5) Move the deflection yoke backward. (6) Bring the long lug of the purity magnets on the short lug and position them horizontally. (Fig.2) (7) Adjust the gap between two lugs so that the GREEN RASTER will come into the center of the screen. (Fig.3) (8) Move the deflection yoke forward, and fix the position of the deflection yoke so that the whole screen will become green. (9) Insert the wedge to the top side of the deflection yoke so that it will not move. (10) Input a crosshatch signal. (11) Verify that the screen is horizontal. (12) Input red and blue raster signals, and make sure that purity is properly adjusted.
