Tempo 1, Tempo 2: 1468 - 1485:
Tempo 1 had been Rock-Ola's first stereo jukebox, introduced Oct 12th, 1958. The model id was extended with a "ST" for stereo. While this model does have a rotating drum for the title strips, shows model Tempo 2 a titlestrip holder with all selections visible at once. Thus a selection can be made faster and there are less pieces involved which can get faulty.
