This document is just what I was looking for, it´s very useful, it contains adjustment procedures for the final stage of the power amp and also
has a complete wiring diagram and description of the main semiconductors used in the design.

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.

Service bulletin # H/K2000-05 May 2000 To: All harman/kardon Service Centers Models: AVR300, AVR500 Subject: Volume Level Changes
Service Bulletin
Warranty labor rate: MAJOR repair
On early versions of the AVR300 or AVR500 the volume level may change by itself, or when the volume knob is tapped. This may happen on an occasional random basis and depends on where the volume control knob is positioned after a volume adjustment. During a running production change, new volume encoders were installed. In the event you receive an AVR300 or AVR500 with the complaint �The volume on my receiver changes by itself�, perform the following procedure: REPLACE VR901 VOLUME ENCODER 1) Remove the top cover, (14) Black Phillips screws. 2) Remove the (11) Black Phillips screws holding the plastic front panel to the chassis. 3) Remove the single Phillips screw on both right & left side of the chassis with a dual black ground wire. 4) Remove the volume, bass, treble and balance knobs by pulling them straight off. 5) Remove the single nut holding the volume encoder to the front panel. 6) Pull the loaded front panel off the chassis; cut any plastic cable ties necessary to fully disengage it 7) Lift and set the receiver on its right side for the remainder of the procedure. 8) Remove molex connector CN983 at the power switch; see Figure 1. 9) Pull the front panel as far away as the remaining connecting wires will allow. 10) Unsolder the connections at the rear of the front PCB to the volume encoder. 11) Using a �stubby� Phillips screwdriver, remove the (19) Black Phillips screws holding the front PCB to the front panel; two plated screws at the rear of the headphone jack also must be removed. 12) Pull the front PCB away from the front panel. 13) Remove and replace the volume encoder with h/k part# J32612050102; resolder the new encoder in place. 14) Replace the front PCB and reassemble the receiver in reverse order, following the instructions above. Replace all cable ties that were cut, and reattach any connectors that were unplugged. Make sure the two ground wires on both sides of the receiver are reattached. 15) Power up receiver, and test volume control to assure it no longer changes settings by itself, or when the volume knob is tapped.
