Dual 701
2-speed automatic single play turntable with electronically regulated direct drive system

Description
The Dual 701 is the quietest turntable ever made. Not only in our judgement, but in that of the first independent test laboratory to evaluate its performance.
This has been accomplished by an entirely different kind of motor, designed expressly for the 701, and a very innovative approach to the problem of resonance.
Instead of the familiar, high speed AC motor, the 701 has an all electronic, low speed motor, with feedback-controlled speed precision.
Because this motor rotates at the record speed, 33 1/3 or 45rpm, the need for speed reduction systems such as friction idler or rim belt is eliminated.
Instead, the platter is rotated directly by the motor, and the record spindle is the top of the motor shaft.
The 701 motor is so quiet and free from vibration that it does not require any isolation mounting, but is mounted directly to the chassis.
Specifications
Platter: non-magnetic, dynamically balanced, detachable 2.9kg
Platter speeds: 33.33 and 45rpm, electronically adjustable
Pitch control: 10% separate for both speeds, each adjusted by means of variable resistor, with calibration scale
Speed control: with illuminated stroboscope
Wow and flutter: < 0.03%
Rumble: < 50dB unweighted
Tonearm: torsionally rigid, tubular tonearm in low-friction four-point gimbal suspension, tonearm counterbalance with two mechanical anti-resonance filters

I have had the turntable in storage while I moved house and did renovations, so it's been over a year since I've used it. I turned it on, and it worked for only a few seconds before stopping: as though the power went out or it blew a fuse. Any suggestions as to what might have happened?
Thanks.

G'day Steve, you might wanna
Submitted on February 4th, 2010 by GanjaTronG'day Steve,
you might wanna check the epoxy (?) capacitor in the gray power supply box inside. That cracked in my 701 and made it literally grind to a halt halfway through a 12". Must be due to thermal stress.
Hope this helps,

My 701 is not functioning properly
Submitted on February 1st, 2009 by stilespjMurgh1,
I could use a copy of the English service manual as well.
The arm will not place itself on the record. It just moves back to the "home" position and shuts off. Also, the speed adjust knobs have no effect now.
Thanks,

Dual 701 - mechanical start /stop problem
Submitted on March 2nd, 2009 by Tony BurchHi Paul
I have a similar problem. The arm is stuck in a mechanical loop: 1) The arm lowers onto the rest and turns off the motor but 2) the platter, still rotating under its momentum, switches the motor on again then 3) the arm lifts off the rest and 4) pauses above the rest for a 3 or 4 seconds, then instead of playing the record, 5) the arm lowers back onto the rest and turns the motor off and the cycle starts again !!!
I have to switch it off at the mains to stop it.
I imagine it is something to do with the arm's automatic start stop mechanism....?
I have asked Murgh 1 for a copy of the english service manual as you did. How did you get on sorting out your problem?

Dual 701cueing problem
Submitted on August 3rd, 2009 by sulshellHi Tony
I was interested to read about the problem with the turntable, particularly since on the otherside of our globe in Australia I am having the same problem. Have you been able to fix it yet. If not maybe we can work together on solving it. If you have fixed it I would be grateful to find out from you how to do the same. You can get me at sulshell@bigpond.net.au

I have exactly the same problem you are having (or had). Did you sort it out. If so, could you please let me know how you solved it? I also asked Muroh 1 for the English service manual but I did not receive any reply.
