Ok, my Pioneer SX-1050 needs a deoxit treament on the volume knob and she will be a right as rain. (She's in extremely good condition otherwise). The problem is I can't seem to find my way to access the volume control. I've taken the case off and the bottom off and still can't see access. Do I need to take the face off? If so, how do I get the knobs off, they seem to be DIY unfreindly. There are two holes on the side of the volume knob, am I correct in suspecting set screws? If so, are they phillips or flat-head? I had no trouble taking apart my other receivers, but this one has me scratching my head just to do a deoxit treatment on one stinkin knob. Please advise. Thank you.
