      Last time I needed a specific pot for a powered speaker that was unobtanium a couple of years ago I found a perfect replacement on Ali.

          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"...

          [Marantz SR5012] Center channel keeps going into ASO/Overcurrent protection.
          by acedogblast
          First off I would like to thank this community as it has provided me with great information that has helped me greatly on my repair for this Marantz SR5012 AV receiver. I am creating this new thread as the other 2 that I have created here has had their original question/problem solved and I plan that this is the final thread on my repair. Please note that this is my first time repairing audio amplifiers so I may not be aware of common issues and things to know.

          Lets start at what I have done so far. Random speaker popping on all channels is fixed by replacing the 2 large filter...

          Marantz Model 150 Tuner "NULL" Adjustment..
          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...

          Marantz SR5007 popping on volume change and mute in Direct Mode
          by BigOof
          Hi,

          I bought a used Marantz SR5007 and it's giving me some issues that I can't seem to really place. It functions well in most settings, ARC mostly works, it has no issues driving my speakers in any of the digital input modes, but I'm having issues running analog inputs in direct or pure direct mode. For some reason in this mode there's distortion for every volume increment I give it, but once the volume is stable it has no issues. Muting creates a loud pop, switching to another source also causes a pop and so does turning off the amp in that mode. Again, no issue in the digital modes....

          by oshimapt
          hello guys,


          first of all i'm not a qualified repair guy, i am a diy guy and as years pass by i have some experience on repairing eletronics, and i'm hoping someone can share their experience.

          i have a marantz sr6012, some times it turns on and works normal, but after a while the sound cuts off or it starts getting distorted and then cuts off.

          when this happens there is no audio no matter the source used, and the OSD shows unknow audio signal from the source.


          i was reading very carefuly the service manual and it is all pointing for...
