Thanks for finding this link somehow, I tried looking for information but could find none, haha. I was messing around with the box and I think I have a better idea of what it does now. I'm pretty sure Ambience "echos" whatever's supposed to go into the rear channel into the left channel also, which probably creates the wide sound stage. If you plug in an mp3 player through the rca input jacks, and disconnect the left or right channel, and flip the switch to ambience mode, the sound still comes from both the speakers but sounds funny. Unfortunately my technical skill is limited, I can't make much sense of the diagram in the pdf. 🙂
Thanks, weirdly seems to sound perfectly fine playing cassettes, so I'm pretty sure someone changed the belts before me.
