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.
 ;
High quality scan of original Service Manual. Everything´s fine!
;
Good scan of the original service manual. All schematics and adjustment procedures are there. It helped me to fix a long lasting problem with the tracking circuitry. The manual also includes the supplementals 1,2 and 3. Included are; electrical schematic's , pcb layout's, mechanical drawing's and exploded views, disassembly manual and maintenance procedures. 236 pages.
;
The Service Manual received was helpful. The electronic information is exactly what I needed.
I recomend all of my friends about this technical page.
