Hi ...
I have a 4 channel car amplifier here to be installed in my car ... but just testing just discovered one of the channel have quite noticable (can be heard) distortion ... if not mistaken it sounds like the transistors were not biased correctly ... and this problem comes and goes ...
i plan to repair this amp myself ... but i dunno where to start to troubleshoot ... but i check already and confirm the preamp sections are ok ... Anyone can help?
TQ
