Features

• Interfaces directly with Ampex 300, 350 & 351 tape transports.

• Accommodates a wide variety of original equipment and replacement heads.

• Solid state monitor and equalization switching eliminates contact noise and permits remote control of both these functions.

• Fully regulated internal power supply assures stable operation despite wide variations in line voltage.

• Plug-in circuit cards combine advantages of both IC and discrete circuitry for unexcelled performance and trouble-free operation.
