Philips PTC 900031. 7 1/2 IPS 4-Track Reel Tape. Made in U.S.A.

This came from a large lot of licensed reels as well as home recorded reels . We have tested a sample of them on a Revox unit and they had fantastic sound. This item was not sampled as of yet because we simply do not have the bandwidth to test them all. Sold as is no return.
Please see my other listings for other items from this great estate.

Thanks for looking.
