Now that I have working tape drives for the Analyzer I find that the
tensioning band in all the cassettes (30 YO ++) I have are blotto.
The tapes themselves appear to be in excellent shape, even after
running several. However, they quickly lose tension whenever they
near the end of the tape. Inspection of the innards shows that all
the bands have elongated holes and have zip elasticity.
Any hints on how to get these cassettes operational?
