Ampex C-60 (circa 1970–1987)

Little is documented about the Ampex C-60 blank cassette tape. The record shows an Ampex-branded blank cassette, apparently in distribution from roughly 1970 through at least 1987. The clearest price reference is Mix Magazine listings in 1986 and 1987, which show “Ampex C-60 blank” at $0.59. A classified ad in Audio (June 1972, p.82) listed Ampex Chrome C-60 cassettes at $2.50. That was a chrome-formulation version, though, and not necessarily the same tape as the later listing.

The C-60 was sold alongside the C-90. Beyond those price-list entries, almost nothing is preserved. No technical specifications have turned up in the available record - no tape formulation, no bias, no frequency response, not even the tape length in feet. There is no period review of the C-60 itself, no service literature, and no confirmed production years.
