Hi to all , I have a problem.on my pioneer sa 8800 where the dc balance on right channel when set to 0 mV result not stable and increase to 100mV..... now I hear in the same channel distortion music....and only after few minutes and after turn off and turn on the power amp again the music going well but is not clean how in left channel.... it is possible the two problem related to the same issue and must be re check and found which is the problem on not stable voltage ?
 
strange fault as it switches channels . no real logic here .. best i can say is deoxit all switches first even if they have been done before ..
if no joy try things like switching to stereo reverse to see if problem switches sides .
