WTB:1 reel used 1/2" tape

[ryangobie]

I still have an otari mx5050 8 track i'm trying to sell and had someone come over today and test it out. i never ran tape through it and it has an unacceptable amount of flutter. like a lot. going to do some work on it, pinch roller, capstan, lubrication, etc... but i need to know if what i'm doing is helping. looking for some tape with some audio on it that i can use to see if i'm making some progress. rather the tape machine be in good working condition before selling. thanks.
