Hi,

Looking for advice on fixing this issue. Playback speed is fine until the tape has played about 3/4, then the speed starts fluctuating, as if it can't cope with the weight of tape on the take-up spool.

I've cleaned and lubricated the idler wheels, and also disconnected and tested the motor run capacitor, which read 2.6uf. Could the capacitor be faulty even though it measures the correct capacitance? What should I try next?

Thanks for any help.
