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.
;
High quality scan of original Service Manual. Everything´s fine!
HTP-650 ADJUSTMENT PROCEDURE
SKW-750 : POWERED SUBWOOFER / ADJUSTMENT OF IDLING CURRENT
[When] 1. Exchange transistors (Q505 - Q519). 2. Exchange MAIN PC board ass'y (NAAF-8829). [Procedure] <Note> No speaker load and No input signal. 1. Short test point P631 for amplifier is under active mode. 2. Adjust the trimming resistor R544 so that the reading of multimeter becomes 52 ohm to 53 ohm. 3. Connect the DC voltmeter to test point P531. <Fig-1> 4. Connect the AC power cord into a wall outlet. 5. Press POWER button to turn on the unit. (MPA type only) 6. Confirm the voltage of above point after 6 minutes to 8 minutes. (Heat running) 7. When less than 3.20 mV : Readjust the trimming resistor above so that the voltage becomes 4.5 mV to 5.0 mV. When 3.30 mV to 5.20 mV : Not necessary to adjust. When 5.21 mV to 10.0 mV : Readjust the trimming resistor above so that the voltage becomes 5.0 mV to 5.5 mV. When 10.1 mV to 20.0 mV : Readjust the trimming resistor above so that the voltage becomes 5.6 mV to 6.0 mV. 8. Press POWER button to turn off the unit. (MPA type only) 9. Disconnect the DC voltmeter. 10. Disconnect the AC power cord from a wall outlet.
