/diy/ - Do It Yourself

I have no idea where else to go with this question. I have two giant sansui 3-way speakers. I moved into my gfs house recently and found an old stereo receiver, technics 'SA-GX710'. I hooked them up and they sounded really good for a couple weeks. Then something strange started happening. Without changing any of the channels, tuning or cables, ect. Basically the issue started slowly but then got progressively worse over time, a dull and quite 'fuzzy-buzzy' sound started coming through. It started soft but now it's really strong and completely ruins all enjoyment. It almost sounds like 'clipping' but it happens continuously and it's not as much of a sharp snapping noise, which usually comes from clipping but rather a more dull and fuzzy sounding buzz. I have no idea how to start debugging this issue, can anyone point me into the right direction. One interesting thing I noticed is when I unplug one of the white/red aux leads, the issue gets considerably better, the buzzing noise almost goes away completely, but I'm not going to just settle for one speaker. The issue also comes and goes, sometimes it completely goes away without messing with anything during the duration of the same audio track, it's very strange. Can someone please help me. Sorry, I posted this in the wrong general earlier.
