Amperex 6DJ8/ ECC88 for free

I have 1 Amperex 6DJ8/ ECC88 tube that I purchased for a headphone amp that I never used. The inside cover states its from 1968 and the measurements are 22.5/ 28.5. I'm not sure if those numbers are any good. It's for free but I only asked you pay for shipping which I guess is less than $10. I hate to throw it away if someone has use for it. Send a PM if interested. Ron
