The Ampex 601 was a portable, analog, reel-to-reel tape recorder produced by The Ampex Corporation from the mid-1950s through the 1960s. Ampex manufactured a single-channel model (the 601) and dual-channel version (the 601-2). The suitcase-sized, 26 lb. unit was designed for the professional recording applications. It recorded to ¼-inch tape on 5-inch or 7-inch reels.
The Ampex 601 was preceded by the Ampex 600. Although there was no officially-released Ampex 600-2, there were factory bulletins available which detailed how to change the second electronics to support the equivalent of 600-2 mode, and this made use of the 601-2's head stack possible, thereby creating the functional equivalent of a 600-2.
The Ampex 601 was succeeded by the Ampex 602, which was available as 602 and 602-2 models. The Ampex 600 and 601 were housed in light brown Samsonite cases. Optionally, the machine could be 19" rack-mounted, using an adapter plate. The Ampex 602 was housed in a dark brown Samsonite case with similar rack-mounting provisions. Companion speaker-amplifiers were also available, and were housed in the same style cases. Models 620, 621 and 622.
