  • Description:

    The Ampex 351 is the double play version of the 300 Series, first introduced under the Irish brand.  These tapes are characteristically VERY thin. The brown oxide appearance is similar to other Ampex tapes like the 341 / 641.  This tape was somewhat popular in the 1960s and early 1970s but are difficult to find in good condition since older machines were often rough with tape handling and many examples have splices, stretches or crumbling. In general, we recommend any 300 Series Ampex or Irish tape for Standard (type 1) applications made with their Ferrosheen process. Notes:

    • As with any thin tape, extra care must be taken when handling as it can easily stretch or crumble under stress.
    • This is a formula that has withstood the test of time. It is amazing to consider that you can make a high quality recordings on a 60 year old tape, but this is indeed possible.
    • 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. Ampex tapes made with their Ferrosheen process seem to shed less today than their counterparts, and should be considered to be at the top of the quality chart for tapes made at the time.
    • The general quality of these tapes increased over their production run as general improvements were made, particularly with oxide shedding and smoothness.
    • Record levels must be set very low to avoid distortion.
    • Available Refurbished: Yes, you can buy refurbished reels of 351 in our store.
