    Service Manuals for audio equipment

    Does anyone know a good place for audio equipment schematics and service manuals?

    Also, how do you go about troubleshooting something without a schematic or SM? I can usually troubleshoot TV ok but amps are much mote difficult, especially since most of the boards in the amps are piled on top of each other, and usually the board I need to test is on the bottom. Once the other boards are removed, you can no longer test anything. Any tips?

    As for your second question, hope for a blown fuse? 8^)

      www.elektrotanya.com also has a fair selection (albeit with certain limitations in usage).

                At one time, audio equipment was easy to maintain and repair (as one book said); now with digital processing/control in modern units, this statement is no longer valid - for such units, having a service manual on hand is generally essential.
                My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

                    by Mark R
                    I am not ashamed to say this is my first FM alignment I have ever done. I am well versed in electronics and repair. Been doing it for many years on Pro Audio Live sound equipment. Worked on Power amps EQ's musical gear and Large format Mixing Live consoles Etc. But now I can see this is a whole different world when it comes to tweaking this kind of gear. I do have the proper gear like the SENCORE SG 80 and HP Generators and Scopes Etc.

                    Look below at Adjustment 12:8. The Null adjustment. I have a Heathkit IM-28 VTVM that was rebuilt and has new Burned in tubes that I used for this...

                    Help troubleshooting an audio problem with an RCA SGT-250 CED Player
                    by samson7point1@yahoo.com
                    The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.

                    The player processes the audio signal using two different reference frequencies. The "R"...

                    Dell XPS 8940 | Manufacturing Mode? | No Service Tag
                    by AustinCER
                    Hello, I currently have a Dell XPS 8940 in our office for repair.
                    Service Tag: HG1Y673
                    The most recent BIOS is pictured below -- being available as an .exe on Dell website.


                    Needed a new motherboard due to power surge. The motherboard replacement was installed and upon power up it was booting to a display message - Manufacturing Mode Active -

                    Have not dealt with this issue before or what the proper steps are. I booted to the BIOS and manually entered the Service Tag, but upon each reboot -- the service tag is wiped and shows the Manufacturing Mode display message,...
