The ease of this purchase was a good start. The content of this manual was exactly all I needed to retore my Tandberg 64.
All of the mechanical and electrical information is contained in the manual and the quality of the document makes reading the data easy.
The exerience with the resource has made this my prime source for technical data.
I found this manual to be complete in every detail. Besides the schematic it has a complete set of alignment instructions which are easy to understand. It also includes a complete parts list as well as an explanation of how the power supply and safety shutdown circuits operate. Even a schematic of the tuner is included.
