Hello.
I am new to vintage audio. I was recently given a Sanusi model 2000. It's not the 2000x or 2000a. The guy who gave it to me didnt even know if it would power up. When i connected it and powered it on, there was no sound coming from the left channel. I turned the balance knob almost all the way to the left and turned the volume 1/3 of the way to full volume. This produced an even volume from both channels, but obviously something is not working correctly. Adjusting the bass or treble knobs or pressing the loudness or mono or reverse buttons has no significant effect on the weakness of the left channel. I have thoroughly cleaned the pot's and switches with deoxit D5, but it made no detectable difference. The cover had previously been removed from the unit and several screws were missing. I was told by a local audio guy that my output transistors might be the cause. I replaced all 4 Toshiba 2sc493 with 4 new MJ15015. This also made no difference for better or worse. What do I try next?
