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.
Drive: synchronous continuous-pole motor with radial elastic suspension
Platter: non-magnetic, dynamically balanced, weighing 3,1kg
Speeds: 33.33, 45 and 78rpm
Pitch control variation: 6%
Speed accuracy deviation: +-0.06%

My favorite tt by far. Ive pieced this baby back into a c 10 plinth with the 12 inch changer spindle and a stanton 680 ee.

If you take a little time using two small metric scales and a strong lighted magnifier to see if the overhang and angle adjustments are accurate, and a test record to check anti-skate and tracking force, then you'll have one awesome sounding turntable. I've had good results using 1 to 1.25 grams tracking force, even with bass drum playback. Great turntable if you're using a tall cartridge as one of the Stanton 680 series, or the Shure M44 types because you can raise the tonearm height.

Great table, sturdy like a tank and has all the things you need in a TT. Automation, size/speed selector, a true workhorse.

My 1229 history goes back to my school days, about 1970. A friend's old man had a 1219. I remember going to his house and admiring the deck. The old man would have killed us (I believe it) if we had ever touched his Dual. He would have had less problem if he'd found us in a compromising situation with his wife, than fooling around with his Dual.
A few years later I was able to afford a 1229. Mine had a neat little flip-down door in the front of the base where you could keep a stacking spindle, and other items. But I never really cared for the Dual, although I can't say exactly why. I think the entire changer scene seemed a bit too complicated and unecessary for me to appreciate. Shortly afterwards, I purchased early Technics DD decks, and they did the trick for me. On the other hand, I always liked the 701 (which I never had a chance to own), and the 704/721 (which I did).
