Very helpful and complete manual. Maybe only one negative is schematics have sometimes unreadable name of the parts. But it's not a big problem.
 ;
Excellent high quality schematics brought my old Heidelberg back to life. Fast download at a reasonable price. Thanks.

This document is just what I was looking for, it´s very useful, it contains adjustment procedures for the final stage of the power amp and also
has a complete wiring diagram and description of the main semiconductors used in the design.

Dear Sirs,
Thank you for the fast support, the manual does provide all necessary information to repair the radio. All schematics are in a good quality for reading.
The manual fits 100% to my requirements as a technican.
Kind regards Thomas

the big video recorder format s-vhs many features delicate in loading system of the cassette. Such machines are no longer manufactured, it would be too expensive.

ADJUSTMENTS OF PURITY AND CONVERGENCE
Note: The final adjustment of CONVERGENCE must be done after the FOCUS adjustment. (CONVERGENCE is changed by FOCUS adjustment.) When makes difference by FOCUS adjustment, should be reconfirming PURITY adjustment.
WEDGE DEFLECTION YOKE
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. � P/C MAGNETS 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.
