I recently found dad's old portable player in the garage recently, changed the belt and cleaned the internals, but the tape still goes out of alignment frequently. I'm guessing that this is a pinch roller issue. but I cant find anything online about this. the only thing I could find is a listing from ages ago. this is also sold in other parts of the world as KT-V860. I want to know the specs and possible find a manual for this. Thanks.
