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

12. To see the amount of dislocation, place the mechanism upside-down. If the stopper bend has been dislocated in the direction of the first CD, turn VR802 to the left(Fig. 2). To lower the stage toward the twelfth step by 0.1 mm, reduce the voltage of EREF (adjusted in step 8) by 10 mV. If the stopper bend has been dislocated in the direction of the twelfth CD, turn VR802 to the right(Fig. 4). To raise the stage toward the first step by 0.1 mm, increase the voltage of EREF (adjusted in step 8) by 10 mV. 13. Place the mechanism horizontal. Go back to step 11 to reconfirm the stage height. 14. When adjustment of the stage height is completed, proceed as follows: 15. Press the EJECT switch. 16. Once operation of the mechanism has stopped, turn the power OFF.
