A good manual! fast service and good qualityi for pdf document.
thanks!

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.
