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.
No 43
Name PHI-1 FILTER
Description The loopfilter connected to pin 43 is suitable for various signal conditions as strong/weak and VCR signal. This is achieved by switching of the loopfilter time constant by changing the PHI-1 output current. Via I2C bus FOA/B, different time constants can be chosen, including an automatic mode which gives optimal performance under varying conditions. To this pin are connected the IC-substrate and horizontal output. The EW drive is a current output. The output is single-ended and is fed directly to the EW-input terminal The vertical drive has a current output. The output is balanced which ensures a good common mode behavior with temperature and makes the output signal less sensitive for disturbances. The PLL frequency range is 32-60MHz with corresponding VCO frequency 64-120MHz. The IF input impedances is 2 in parallel with 3pF and matches the required load for commonly used SAW filters. A DC coupling is allowed, so no series capacitors between SAW filter and IF input are necessary. The input range for EHT tracking is 1.2 ~ 2.8V, for a compensation of +/- 5% on vertical and/or EW. The tracking on EW can be switched on/off by HCO. The overvoltage protection is activated when the voltage on pin 50 exceeds 3.9V typical. This pin requires a capacitor to ground of l00nF +/- 5%. The optimal sawtooth amplitude is 3.5V and is determined by the external capacitor and charge current. The sawtooth bottom-level is 2V. This pin requires a resistor to ground. The optimal reference current is 100 . which is determined by this resistor. The AGC capacitor value is 2.2 and has been defined for an optimal compromise between AGC speed and tilt for all AGC modes (negative/positive modulation). This output is used to control (reduce) the tuner gain for strong RF signals. The tuner AGC is an open collector output which is acting as a variable current source to ground. not used. This pin requires a capacitor of 10 connected to ground. The pin acts as a low pass filter needed for the DC feedback loop.
