Technics/Panasonic RDG5773Z Gear

While a typical problem of Technics/Panasonic tape drives is the RDG5772ZC gear, sometimes might crack also gear located at the opposite side of the tape drive (down side) – RDG5773Z.

Either the lock can be broken or the shaft.

Replacement gear was created using a precise 3D printer using durable Nylon material. Locking mechanism was replaced with a split pin to be less fragile
