@leemurray2007 Have you contacted ATR Magnetics?
https://www.atrtape.comTo my understanding they are the only US manufacturer still making cassettes.
Why would you even think of doing this? Anyway you’ve come to the wrong place with your endless questions about a dead medium. There are actual forums for tape junkies. Find one.
