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
higher than necessary to obtain a clear pattern. Converge the red and the blue dots at the center of the screen by rotating the R&B pole static convergence magnets. Align the converged red/blue dots with the green dots at the center of the screen by rotating the R &B&G pole static convergence magnets. Melt wax with soldering iron to reseal the magnets. Slightly tilt vertically and horizontally (do not rotate) the deflection yoke to obtain a good overall convergence. If convergence is not reached at the edges, insert permalloy in the DY corners to achieve proper convergence. Recheck for purity and readjust if necessary. After vertical adjustment of the yoke, insert wedge at 11 o�clock position, then make the horizontal tilt adjustment. Secure the deflection yoke by inserting four side wedges. Apply adhesive between tab (thin portion) of wedge and CRT and place tape over the tab to secure to the CRT.

Use this for a precisely overall convergence adjust at the edges. DY(YHC, YV, XV) ADJUSTMENT YV ADJUSTMENT / (VR1 FOR HORIZONTAL DYNAMIC CONVERGENCE)
