Here's picture of my Unisef; what is the rarity of these and should I sell it? I ask because the left speaker does not work and there is no loose wire when I checked it out. It looks very nice and would hate part with it if I cannot fix the speaker even though someone has offered me $20 for it. Any suggestions on the cause?

I hope this is the correct topic forum to ask.

did you test the speaker its self. also try cleaning all the controls as well.

Thanks! I will do that and test the speaker which I had no thought about doing. I guess the obvious solution is sometimes missed!
