Technics SL-1650
(1977 - 1978)

Here is something that vanished completely: record changers.

Up to six records can be loaded on the umbrella-like spindle. The Memo-Gram selector allows to program any sequence between records: with three discs loaded, if set to "4", the last side of the tird disc will be repeated once ; with six discs loaded and the Memo-Gram set to "4", only the first 4 sides will be played. And if set to "R", the last side of the last record will be played repeatedly. Ad nauseam :)
In single-disc mode, the Memo-Gram settings alternate between repeat of a side up to six times. Or repeatedly, continuously and passionately.

Of course, auto-reverse wasn't in the program, but the SL-1650 was built like any big turntable: the rotor and platter are combined into a single piece, a B-FG speed monitor which stands a 30g load without loss of selected speed, zinc-alloy tonearm base and aluminium die-cast turntable base.
Further features are a double-insulator system, a 10% pitch control for each speed, a strobeobscope lamp and a (very basic) variant of Technics' fine EPA-100 tonearm. Said tonearm, however, isn't supported by a motor of its own, but is fed by that of the turntable.
