Produced through to the early sixties, the 601 was announced by Ampex as “at last, true Ampex
performance in a 26lb miniaturised professional package”.
Available in single and later double channel (the 601-2, pictured ), it utilized three heads and a single motor.
Price in 1960 was about $US600.00 for the single channel model and $995.00 for the half-track. To get an idea of just how much that was, you could buy the top of the range Sony CS-300 stereo recorder for $390.00,
a Tandberg model 6 for $490.00 or a Knight KN4310 for $240.00 And while you were at it, why not add a couple of 620P’s – a matching portable amplifier and speaker unit with a 10 watt output and a 65 – 10kHz acoustic response – a mere $190.00 each!
