Help with what? It sounds like the receiver is in need of service.

The tuner section of your receiver (?) is used for radio reception. A "receiver" is a term which describes a tuner, pre amplifier and power amplifier packaged together on one chassis. I assume you own a receiver but do not use the tuner. And, still, it sounds as if it is in need of repair. Are you asking one of us to tell you how to do the repair yourself?

Is the ringing in both channels?

To isolate the problem disconnect all external components (cdp, tape deck, speakers, etc.). Plug in the headphones and listen for the ringing. Switch to the various input positions to determine if the ringing occurs in all input positions or only certain ones. If you get the ringing in all or only certain input positions the problem is the receiver.

If you don't get the ringing in the headphones connect your speakers. If you don't hear the ringing through the speakers the problem is, obviously, not the receiver. Then start adding other equipment one piece at a time to see when the problem comes back.

I have seen devices that develop a feedback problem in the preamp or output stage causing a "ringing" sound but it is usually only in one channel. Verify whether it is in one or both channels.

Let me know what happens.

Seems as though a trip to the repair shop is due. Keep us posted.

Seems like the advice is get the unit repaired. If that's not what you wish to hear, the advice then would be to get the unit replaced. Those really are the only two options for you right now. Expecting us to tell you how to repair this unit over the forum is a bit beyond the ability of anyone here. Repairing audio gear is something you must understand and you must have the particulars of a shematic and knowledge of the unit before you. It requires test equipment that we cannot employ over a forum. It is not a plug tab "A" into slot "B" type of affair. Had we told you to replace R13 would you know what that meant? If you, yourself, do not know how to troubleshoot the problem, we certainly cannot be expected to perform that task over a forum. This may sound harsh but, please, understand what you are expecting us to do.

At this point, if you want the unit repaired, you must take it to a repair facility. If you don't want it repaired and would rather buy a new receiver, you should proceed with that task. We cannot repair this unit for you and it would be foolhardy for us to suggest to someone unskilled in electronics they should place their hands inside a component.

if you do know what R13 is, and feel like where telling you to stick it in your C1, sorry, were not (even if you don't know what those are). Jan is right that this forum can only take you so far.

the real technical geeks run over at www.DIYaudio.com

check them out, they definately can get to the nitty gritty on your problem, but it will require some basic electronics and circut board type knowledge on your part.

good luck! Perhaps if you posted where your from (general area) someone in these forums could direct you to a reputable repair shop they know of.

cheers!

As I stated in my previous post your problem could be a feedback in the pre-amp or output circuits but it is rare to have the same problem in both channels at the same time. I have repaired equipment with "ringing" in both channels but the problem was always a ground loop - ground being common to both channels.

Since the "ringing" occurs regardless of the input selected it is definately an output rather than an input problem.

It's time to repair or replace...as another poster stated. Good luck.

Bottom line is that it needs service.
But the analitical side of me is curious.
What is your definition of ringing?
Is it a steady tone?
High pitched or a lower frequency hum?
Does the volume of the ringing change with the volume control or does it always stay the same?
Varies, is in the preamp portion before the volume control.
Fixed, is in the power amp portion after the volume control.
Since it is in all input selections it must be after the input selection stage.
The one thing in common with both channels is the power supply. But usually any power supply noise would be 60 or 120Hz hum.

More than likely "oscillating" would be appropriate.

Making assumptions often takes one down the wrong path.
Maybe it really is a ringing.
You're probably right though.
