These 8 track tapes have been Tested some get tested for longer then others depending on what I?m doing at the time usually while im working some might be playing for hours either way none of them will have new pads or be repaired these will be in there original state  i can?t guarantee these will work perfectly on your end all my equipment has regular service cleaning new belts and whatever parts need replaced get replaced all i can tell you is i will sample them i do not believe in sending out bad media to make a sale music is supposed to be enjoyable not a disappointment these will be as is a lot of people already know how to repair and rebuild these 8 tracks so it is possible to have an upkeep on one with that said i hope you enjoy what your getting thank you no returns on these
