Just finished refurbishing my fathers old (late 70's) Sony TC-765 and wanted to get a new tape, rather than the old ones that my father had, most of which were shedding.
I bought one of these and was amazed at the recording quality, even at 3 3/4 ips.
If you need a fresh tape, you won't go far wrong with these. Needless to say, i will be buying more in the near future.
