  • Description:

    Scotch 150 and 190 were introduced in 1954 as the long play tapes, and have the characteristic red oxide formulation. This was a very popular tape back in the day, so they are often found in garage or estate sales. It was produced until 1972 for an incredible 18 year production run.  Notes:

    • Performance will be similar to the Scotch 150.
    • As with any Acetate backed tape, the 190 presents long term usage and storage challenges. The Scotch acetate tapes seem to hold up better than other brands (with the exception of Audio Devices / Audiotape) but should not be considered reliable choices for daily use going forward. Their quality today is directly rated to the way they were stored.
    • Tapes of this vintage have a tendency to shed oxide more than modern tapes. This is not a sign that this tape is degrading, it should be considered normal.
    • The general quality of these tapes increased over their production run as general improvements were made, particularly with oxide shedding and smoothness.
    • This tape formulation was often used for commercial tape duplication.
    • Available Refurbished: No, we do not sell acetate backed tapes as refurbished.
    • Available Used: We offer select Scotch 190 that we have inspected for condition for those who want this tape for their collection or for their own testing.
