Take up spindle is not turning--tape comes out of cassette
I have a Sony M-450 microcassette recorder that I just bought on eBay. It appears almost identical to the M-430.
For approximately a minute the tape played properly but then the tape stopped playing. When I opened the tape door, a lot of tape had come out of the cassette. On studying what was causing it, I realized only the supply spindle is turning which just keeps pushing the tape out of the cassette and it is not being taken up by the other reel.
Would that be caused by a stretched drive belt under the motherboard? Thanks if you can help.
Is this a good question?
