Hello, I’m pretty new to AK, so this is my first post. I very much need a volume control for my pioneer sx-1050. If anybody out there has any leads or assistance they can offer it would be greatly appreciated.
Thank you

Hi, can you give us a little more info? What is your level of expertise? How do you know the volume pot needs to be replaced?
 
First, I would make sure some of the other controls aren’t the problem. The SX-1050 I had, had an issue with the 30 Hz button causing one channel to drop out, especially at low volumes. I would operate all of the controls multiple times while experiencing the issue with the volume control to see if it goes away.

Unless the shaft is snapped off, volume controls usually don't "Fail", but they can get really dirty causing the volume level to be scratchy, with one side, the other side, or both to drop out when turning.
The SX-1050 uses a sealed volume control, so its not easy for someone without experience to clean it.
To get to the control, the cover has to be removed, the front panel and knobs have to be removed, and the board with the volume control needs to be pivoted out of the chassis, to get to the 2 screws that hold the control together. Those screws, and small nuts behind have to be removed, and the sections need to be carefully pivoted open just enough to spray some cleaner, and then some faderlube into the openings. I believe there are 2 sections to that control, but could be 4. Advising again that if you don't have experience with things like this, find someone who does.

My level of expertise is limited, but I’ve handed it off to my tech, and he has cleaned it multiple times and rebuilt it, and still the right channel will drop in and out. Very frustrating.

I will definitely have my tech look into the 30hz switch. Thanks for the reply

It’s been handed off to my tech who has cleaned it multiple times as well as rebuilt it. Still the right channel goes in and out.

But what did he clean? Are you sure it isn't the selector buttons causing the issue? Those are very touchy and flaky on these models. Really, the problem could be caused by almost any of the switches or buttons on the front panel.

Sorry, he cleaned the volume control multiple times and rebuilt it. Not sure if he cleaned any of the other controls actually. It seems he is confident the volume control is th culprit.

Does the problem go away or lessen when you switch to mono? Try cleaning all the controls on the front. Flood them with contact cleaner and follow up with electronics lube. I use the stuff from Home Depot. You have to remove the faceplate to do this, and it's somewhat time-consuming, but it may fix your problem.
 
So we don't assume that your tech is incompetent, but can you tell us what he knows or what he knows to look for? Because if your tech can't find it............:idea:

Intermittent dropouts that I have ever experienced are not caused by parts themselves but rather loose connections, dirty pots and switches, dirty contacts of the speaker relay, cold solder joints, and/or broken traces.

It does stay the same in mono mode.

I have confidence in my tech, but no one is perfect, so knowing the right questions to ask is definitely helpful and perhaps one of these plausible failure locations could have been overlooked or perhaps or in need of a second look.
 
Your tech doesn't sound very competent.

If ALL switches haven't been cleaned, and the relay hasn't been replaced, there's potential for issues.
 
Relays are a very common failure. You could open the receiver, play music at a low level, and wiggle the relay. If the sound in one or both channels comes and goes, it needs to be replaced.
