Nice initiative!
Is there maybe something similar going on for Duals first belt drive, the 601?

This 701 initiative is the first collaborative effort that comes from two major Dual sites. It does not matter if you register your 701 on the dualbord.de or here on Vinyl Engine, it will be recorded.

The choice of the 701 was started on dualboard and makes sense since the 701 was really the first high end direct drive unit from Dual, a mile stone to be sure.
The 601, launched just after the 701, is also a milestone, as it is the first belt drive. It has a bid of a bad image because of the motor issue when used on the 60 Hertz power systems. Perhaps a bit later we could get the 601 database up and running as well.

There is however another far more important Dual unit, that must get the same worldwide respect.
Perhaps we can lead the way with this unit.

Any guesses as to which unit I'm referring to?

k

Hi,
The litz cable, I presume was changed from the original.
This is one of the conundrums on the 701. Going by the serial number, it should be a version 1. The CD4 and presumably the lo-cap wires, put it into version 1.1.
Can you check to see if the white AS oval and nut (items 70 and 75) under chassis still has the original glyptol (red or blue) seal?
As I recall, service departments did update units as I did with the servo board. It is not unusual for the unit to have been changed to lo-cap cables and fitted with the newer AS wheel. What does give it away is that the factory seals where broken and visible, even though we used the same glyptol to reseal.

Regards,
k
The bias/anti skating parts appear to have the seemingly original seal on and no 'obvious' sign of ever being replaced. Tonearm cables also look original too and to be honest in the UK, I can't ever have seen the importer (Farnell at the time?) pulling brand new decks from packing boxes to modify. Maybe they did, but I'd have thought the US would have taken up with the whole 'Quadrophonic' thing before we did. I call the tonearm cables 'Litz' as they're kind of twisted and/or woven together. they're the same wires the 601 uses so original' Dual' I think. I replaced the exit cables to the amp many years ago but have never disturbed the tonearm wiring loom.

My deck was originally offered for sale with the cartridge it was traded in with, a Stanton 681EEE, which I didn't need so it was taken off before I took the deck away. I'm assuming the deck was bought new with the 681EEE and used as such for a good few years - this cartridge has no need of low-cap wiring.

I will give it a try! :-k

I am going to suggest the original 1009.
Even though some later idler variations and models get more accolades they were all refinements of the 1009 design.

I would suggest the 1019, as being the most refined idler changer of its time.
Cheers,

Hugh.

What, better than the slightly earlier Garrard Lab 80 models? Don't knock the Garrard tonearm - it's a lot better in practise than it looks! the Lab 80 drive is quieter than my 1019 as well...

S'alright, I love my 1019 :D

Another nod towards the 1009. Not so much on the basis of technical arguments, rather due to its importance commercially in establishing Dual.

Hi,
A slight correction:
Richard is in Australia not in the US- Sorry Richard -my mistake!
043507 - ritchearth (Aus) Vinyl Engine

...and another 701 entry,
701, sn 074100, ver, 1.2 , "Uwe" (D)
I'll repost the updated list when we get a few more entries.

A picture of the Star:

As for the next "accolades deserving" Dual, yes, the 1009 is on my (admittedly biased) mind!
And yes, it is primarily because that unit launched Dual over the top and started the Dual "uproar" worldwide.

The PE 33 (and subsequent 34) was every bit its equal and in some respects superior, as it has a combined belt and idler drive, (a PE design), and a magnetic brake type pitch control, both reminiscent of the Thorens TD 124:

but the overall design and super clean looks made the 1009 a knock out sales runner:

Interestingly, the 1009 incorporates the auto mechanism design from the 1007/1008 almost to a tee. The main changes are of course, the vastly improved arm, an improved (can) motor and a simplified speed and size selector, besides bringing the new norm of styling for future Duals.
What we did loose from the much more complex 1006 and its variants, is the "idler off" position on the speed selector, preventing idler flat spots, a constant speed automatic system, whereby the arm movement was at a constant speed, no matter which speed (16 to 78) the motor/platter was set at, a built in cartridge tracking weight scale, a Mono / Stereo switch and a plug in preamp or factory installed preamp.
The 1006 etc. had a heavy cast platter and a four pole motor much like the 1218 brick motor as well. The 1006 arm's auto size sensing mechanism makes the 1219/1229 tonearm mechanism almost look like child's play...
So why the 1009, again, the simplicity, robustness and looks in a package that could equal any "manual table" at the time, coupled with a full automatic changer system.
The next gen of these units, like the 721 or the 1019, certainly brought very desirable features, but the initial offering is still the ground breaker- and so it is for Dual's first belt drive, the 601 as well.
There is another bit to the 1009 which deserves more investigation once we launch an Owners List drive (perhaps after the holidays?).
More on this later but in the meantime, keep those 701 serial numbers coming!
Regards,
k

Hi Klaus,

Thanks for the correction and greetings from 'down under'!

But I'm afraid I have to burden you with another correction: my 701 has the CD4 anti-skate dial, low cap cable and relay, which would put it firmly in version 1.2 on the dual board list, not 1.1 as I first submitted. Apologies.
