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.
