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

the big video recorder format s-vhs many features delicate in loading system of the cassette. Such machines are no longer manufactured, it would be too expensive.
 ;
THIS MANUAL IS VERY GOOD AND VERY CLEAR
PLEASE NOTE IT DOES NOT CONTAIN THE SETUP INFORMATION TO ALIGHN THE GEARS IN THE CD MECH IT DOES SHOW ALL THE PARTS AND THEIR LOCATIONS .
;
Complete service and operation manual. All schematics are there, all circuit boards AND add-on boards. Including exploded views ,component names and specifications. Also electrical and mechanical adjustment procedures are in this manual. This manual also covers the more advanced BR-S811E unit. Scan quality is fair and usable.
