3-Speed Idler Drive Turntable (1972)
With the 1229, Dual has achieved what many audio experts have called the no-compromise automatic.
The most dramatic example of this is the mode selector that shifts the entire tonearm base - down for single play, up for multiple play.
Thus the stylus tracks at precisely the correct angle in both modes of play.
The 8 3/4 inch tonearm, the longest of any automatic, tracks flawlessly at as low as 0.25 gram.
Other 1229 features include 12 inch a dynamically balanced 7lb platter, powerful continuous pole / synchronous motor, built in illuminated strobe with adjustable viewing angle and a calibrated tracking pressure dial.
The unit has 3 speeds with one semitone pitch variation on all three speeds and the torsionally rigid, extra-long all-metal tonearm features four-point Gimbal type bearing.
