I hope that you're upgrading more than just restoring the Otari.I wouldn’t bother with $400+ tapes for mine.

Audiophile Reel to Reel Tape
There was a recent article in either Stereophile or The Absolute Sound that listed the companies that sell and titles of Audiophile 15 ips reel to reel tape available,. I am unable to locate it, does anyone know what month or issue it came out? I am getting back into reel to reel and in the process of getting my Otari reel restored. Thank you...
