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
