I PURHASED THIS PRODUCT BECAUSE I WAS HAVING PROBLEMS WITH MY CDR20 HARMAN KARDON RECORDER. WHICH I PURCHASED NEW 12 YEARS AGO. AFTER REVIEWING THE MANUAL, I WAS ABLE TO ADJUST THE TENSIONER IN THE SYSTEM. WORKS LIKE A CHAMP!.
SAVED ME AT LEAST 100.00 WHICH WAS WHAT A SERVICE REPAIR STATION WANTED. GREAT MANUAL EASY TO READ. SPECIALLY AFTER I PRINTED THE PAGES WHICH DEALT WITH MY RECORDER. THANKS A LOT!!!!!!!!

You can fully trust on this one!
All the schematics are very crear an in one piece per page

The manual I purchased was just what I needed. I was glad to find a site where I can find so many manuals on a wide variety of products.
NOTES In many cases, color misconvergence may be corrected by returning HIT and WID data in main deflection side to initial adjusting values. Following cases will surely require readjustment of convergence. CRT REPLACEMENT When CRT is replaced, main deflection readjustment and color matching are required. Perform following procedures. 1. Replace two CRT�s of blue and red. 2. Perform horizontal adjustment for blue and red yokes on base of green CRT data. Mount yoke and velocity mod. coil alignment, pushing towards CRT without gap. 3. Adjust alignment of blue and red. (Refer Alignment adjustment for details.) 4. Rotating centering magnet, adjust CRT centers of red and blue to CRT center of green. (Picture position adjustment) 5. Adjust HIT and WID data of main deflection, and decide data at the most precise screen comparing to green data. 6. Adjust convergence of each screen picture for color matching. Do not move green one at this time. 7. After convergence adjustment of each screen picture finishes, replace green CRT. For green CRT as well, repeat steps 2 to 5 above on bases of red and blue color matching to adjust convergence. REPLACING CONVERGENCE UNIT When replacing convergence unit, all picture screens require readjustment basically, but the following method allows process be reduced considerably. 1. Replace the memory (Q713) on defective unit with memory on new unit. Mounting the unit on the SET after the above working realizes picture screen before replacement immediately. 2. Mount unit which has combination of old and new memories, on SET and turn it on. Screen shows whole picture looks like straightly shifted towards vertical or horizontal direction. 3. Adjust again centers of green, red and blue with centering magnets. 4. Check each picture screen for slight disparity of color and picture size. If necessary, add some adjustments of main deflection and color matching of convergence.
