Hi All,

This may sound silly to some of you, but I have a Harmon Kardon stereo reciever from around 1991. Model # HK3400 stereo reciever.

The right speak doesnt have sound, if i jiggle and move around the balance knob, it gets static and at times starts to get the sound and volume it should but never lasts. I hardly ever used this reciever and hope it's just a simple thing.
Can anyone advise me what it could be and how to fix it?


Thanks
Tim
