This is a pair of TEAC 66903 heads; these are fitted to some members of the A-4010 family, and perhaps others. Please check compatibility before purchase.
These came with a lot of parts, so I haven't had the opportunity to play a tape with them. They're cosmetically excellent, with light to medium wear and electrically in good shape; all four coils test at 130-135 ohms DC resistance.
This will ship 1st Class or Priority Mail as you choose.
