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.

Description
For the connection of the pickup photodiode. Addition to the FIN1 pin creates an RF signal and subtraction from it create an EF signal.
O O
For the connection of the pickup photodiode. For the connection of the pickup photodiode. Subtraction from the F pin creates a TE signal.
O I O
For the connection of the pickup photodiode. Inputs the DC components in the TE signal. For the connection of a resistor which sets the gain of the TE signal between this pin and the TE pin.

TE signal output. TES (track error sense) comparator input.The TE signal is passed through a BPF. Shock detection input. Sets the time constant for the tracking gain. TA amp output. Composes the tracking phase compensation constant between the TD and VR pins. Sets the tracking phase compensation. Sets the amplitude of the tracking jump signal (kick pulses). Tracking control signal output. Focusing control signal output. Composes the focusing phase compensation constant between the FD and FA pins. Composes the focusing phase compensation constant between the FD- and FA- pins. Composes the focusing phase compensation constant between the FA and FE pins. FE signal output. For the connection of a resistor whichs sets the gain of the FE signal between this pin and the TE pin.
