Hello.
I am having some trouble with my stereo system, and need some help.
I am occasionally getting "static" on one channel. I put static in quotation marks because I'm not entirely sure that's the right word for it. When the problem occurs, the sound from that channel is extremely static-y/distorted, for lack of a better phrase. It is not a subtle issue; when it's messed up, it sounds horrible in a very obvious manner.
It is not "random" static, because the music itself is discernable behind the mess. I can control the volume of the "static" just as with music; turning the volume down on my integrated amplifier (Technics SU-V10X) eliminates it, just as it quiets the music in the other channel. When the volume is all the way down, no sound comes from either speaker, just like when there is no problem. If the "static" is present, I can also eliminate it by simply stopping playback at the source (eg, lifting the tonearm off the record, hitting the stop button on my tapedeck, etc). The "static" will return when I start playing something again, until it magically decides to go away.
The first time it happened, I thought something was wrong with my speaker (blown, I guess). I quickly turned the integrated amp off, as I didn't really know what to do. Some time later, I tried to play music again at a very low volume, and was quite surprised that everything was functioning normally.
A week or two later, it happened again (this was after many many hours of use, as I constantly have music on). This time, while the problem was present, I switched the wires connecting my speakers to the integrated amp (I left the wires in the back of the integrated amp, but switched which speaker they were connected to... so my normal R speaker was hooked to the L output, and vice versa). The "static" switched speakers when I did this, which tells me that the problem is not in the speakers.
When present, the "static" is also not affected by which input I am using. If it's present, I can switch between phono/tape/cd, and it wil still be there for all of them.
I read some old threads on here where people mentioned jiggling the controls on the front of the amplifier, and whether that had an effect on the noise. It does not affect the "static" for me. Music (a signal) is the only thing the "static" seems to have any correlation with.
I feel (hope) like the problem is just a bad connection somewhere. The speaker wire going into the back of the integrated amplifier (under the caps) was ugly-looking (silver/grey instead of shiny copper--oxidized?). I cut that part off and pared down the wires to expose shiny copper, and hooked them back up. That took care of the problem for about three weeks, but it just happened again. :sigh:
OK, so after all that, I'm basically wanting to know if a "bad connection somewhere" is the likely culprit, or if these symptoms are consistent with an actual problem with the integrated amplifier. If a "bad connection" is likely, is the next step to do what is outlined in this thread? (deoxit: http://www.audiokarma.org/forums/showthread.php?t=207005&highlight=deoxit&page=14). Are there other things I should be doing?
Thanks for any help.
