***Don't forget to check your 8 tracks for worn or deteriorated pressure pads. Many 8 track tapes will need these be replaced for proper operation. Often without good pressure pads the tapes will be eaten so take heed*** It is true that it is always a defective tape NOT the player that causes tapes to be "eaten"
