I needed a service manual as the display on my oscilloscope was very dim. I thought I'd give owner-manuals.com a try, as they advertised a huge number of manuals. Sure enough they had one listed. I bought it hoping it would be useful... actually, I bought it hoping it would be readable! I've had manuals from online sources in the past, and been very disappointed. Not this time! An excellent manual, complete, and very readable. Using it I fixed my 'scope, and as such the manual was an investment that paid off manyfold. Do I have any complaints? One very minor one - The circuit diagrams could have been scanned at a higher resolution, as some of the details were a little difficult to make out - not impossible, just not as easy as my old eyes would like! Overall, I'm very satisfied with my manual, and I will certainly be using this company again. Well done.

I Have looked for this manual for quiet a while now, I have finally found it here. I believe this is the only place they have them in a very nice scan, pages are very clear to read, some of the pages are a bit tilted but overall it is great to have this manual available for purchase. Thanks

9. SUB-BRIGHTNESS ADJUSTMENT
1) Tune in a color program. 2) Set the CONTRAST control to maximum and the BRIGHTNESS control to maximum and the SHARPNESS control to the center position. 3) Set the COLOR and TINT controls to center. 4) Set the SUB-BRIGHT control R554 to center and leave the receiver on five minutes in this state. 5) Watching the picture carefully, adjust the SUB-BRIGHT control in the position where the picture does not show evidence of blooming in high brightness area and not appear too dark in low bright area. 6) Check for BRIGHTNESS controls at both extremes. 7) If the picture does not appear dark with the CONTRAST and BRIGHTNESS control turned to minimum, or not appear bright with the controls turned to maximum, adjust the SUB-BRIGHT control again for an acceptable picture.
10-1. COLOR PURITY ADJUSTMENT
NOTE : Before attempting any purity adjustments, the
receiver should be operated for at least 15 minutes. 1) Demagnetize the picture tube with a degaussing coil. 2) Adjust the CONTRAST and BRIGHTNESS controls to maximum 3) Adjust RED and BLUE Bias controls (R971 and R973) to provide only a green raster. Adjust the GREEN BIAS control (R972) if necessary. 4) Loosen the clamp screw holding the yoke, and slide the yoke backward th provide vertical green belt(zone)in the picture screen. 5) Remove the Rubber Wedges. 6) Rotate and spread the tabs of the purity magnet (See figure 2) around the neck of the picture tube until the green belt is in the center of the screen. At the same time, center the raster vertically. 7) Move the yoke slowly forward until a uniform green screen is obtained. Tighten the clamp screw of the yoke temporarily. 8) Check the purity of the red and blue raster by adjusting the BIAS controls. 9) Obtain a white raster, referring to CRT GRAY SCALE ADJUSTMENT 10) Proceed with covergence adjustment.
