Good site, works ok and you get what you order, no problems experienced, got my manual within a day. A++++

Original well scanned manual. Got the job done. Microwave problem found & corrected. For $5 and a new magnitron from ebay, it was a cheap and good the first shot fix. Electrical schematics allowed me to mage sure every thing else was ok before cutting and order for parts. Hard to live without.

I was very skeptical of this website, I have never downloaded manuals before. I put it on the AMEX and payed through Paypal to ensure protection. I got the manual exactly as described and now I can replace the filter capacitor for this amp. Great Price, others selling for 12.99 or more and this is the same manual. I will search out this website for other manuals. Thank you

Manual was reasonably easy to follow. I am not an engineer or know much about electronics but with the manuals help I was able to figure out the problem, identify the part required for the repair. Replacement part cost around $30. Whilst replacing the part I was telling myself, "this aint gonna work cos it seems far too easy". Took about 15 minutes to do and my plasma TV works a treat. Would never have been able to do this without the service manual.

Service bulletin # H/K2003-10 December 2003 To: All harman/kardon Service Centers Models: AVR130, AVR230, AVR330, HK3380, HK3480 Subject: Volume Level Changes
Service Bulletin
Warranty labor rate: MAJOR repair
On early versions of the AVR130,AVR230,AVR330,HK3380,HK3480, when the volume control is turned, the volume level and display may be erratic, and not track accurately, or the level may progress in an unintended direction. This may happen on a 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 AVR model listed above with the complaint �The volume control on my receiver does not track accurately when turned�, perform the following procedure: REPLACE VR74 (AVR130/230/330) or VR81 (HK3380/3480) VOLUME ENCODER
Note: It is important that the various screws do not get mixed up and inserted in other locations upon reassembly. Make note or label each removed screw set; keep them apart from other screw sets.
1) Remove the top cover, (13) Phillips screws. 2) Remove the volume, bass, treble and balance knobs by pulling them straight out and off. If a tool is necessary for removal of the smaller knobs, make sure the jaws are insulated to avoid knob damage. 3) Remove the (10) Phillips screws holding the front panel ass�y to the chassis: (6) at the bottom and (4) at the sides. 4) Cut all plastic cable ties that would prevent you detaching the front panel ass�y from the chassis. Draw a diagram if necessary, for a location reminder, to aid reassembly. 5) Unplug connector CN15 (6 cond) or CN89 (7 cond) at the left side of the unit. See below. 6) Remove single ground screw at the left side of the unit, near CN15 or CN89. (Black wire) 7) Unplug connector CN72 (32 cond) or CN81 (20 cond) on the DSP PCB, coming from the top of the front panel ass�y. See below. 8) There should now be enough slack in the connecting cables to lift and detach the front panel ass�y from the chassis. Pull the front panel as far away as the remaining connecting wires will allow, enough to tilt and gain access to the rear of the Tone/Volume PCB. See illustration Page 2. 9) Remove the (10) screws or (9) screws holding the Tone/Volume PCB to the front panel. 10) Detach and pull back the PCB; unplug top connector CN84 (7 cond) or CN83 (4 cond) if necessary. 11) Remove and replace VR74 or VR81 (5 soldered pads) with hk part# HSR2A029Z. 12) Reassemble in reverse order, taking care to replace all connectors, cable ties, and ground screw. 13) Power up receiver, and test volume control to assure setting no longer changes settings by itself, or when the volume knob is tapped.
