  • Description:

    The Ampex 642 LP (long play) tape is a newer low noise / high output formulation produced by Ampex and the Quantegy from the 1980s and then by Quantegy until they closed down in 2007. This tape was not back coated and did not have sticky shed. The performance is similar to Maxell’s UD. It was also sold by Radio Shack in the 1990s through the 2000s as their sole (and last) reel to reel tape.   Notes:

    • This is a formula that has withstood the test of time. It is reliable and can be used today.
    • The quality of this tape is high, with excellent stability and low oxide shedding.
    • They were shipped in a variety of packaging and reel designs, and the Radio Shack private label versions should be included.
    • Available Refurbished: Yes, you can buy refurbished reels of 6421 in our store and they are highly recommended.
