[Hidden-tech] Stereo Guru?

[B. Kimo Lee]

Hi David,

I'm not an electronics technician, so someone else may have a more  
technical solution/explanation. I also had a similar experience with  
one of my previous systems a while back. In that case, it turned out  
that the speakers were going. Fix was to have Boston Acoustics send me  
replacement speaker parts. Try plugging some other speakers into the  
system to see if the problem goes away.
In another case with an older stereo amp, whenever I turned the volume  
knob, it would make the audio crackle. That was solved by working some  
WD40 into the knob spindle while turning it back and fourth. That was  
a Macintosh. I guess newer systems are all buttons, eh? Well, I hope  
it's just your speakers and not some transistor or other electronic  
part.

Best,
Kimo
