How To Clean And Lubricate 1970's Vintage Dual Turntable

A brusque while agone I received a few turntables from a client for restoration. They consisted of 1019, 1219 and a 704, plus a 1009sk.
The 1219 had some transport impairment merely substantially it was a normal make clean up without dearing band damage. The 1019 which I am now doing is also a straight forward restoration and I will put the moving-picture show serial on my web page as presently as information technology is finished.
Now for the 704...
The client wanted to ensure that the unit of measurement would run for a long time, so he endeavoured to lube it a bit himself. The 704 is different in the pattern in many ways from the Dual rim or idler drives. The first detail to note is that these directly drives have motors that should not exist re lubricated. This is because the motors are turning at the record speed (33 or 45) and therefore there is no wear on the rotor. If whatever other oil than original brand is used, the oils tin cause deterioration due to the unlike additives and types of oil.
The 704 arm is an infinitely VTA adjustable arm which uses wacker silicon oil AK 500 000 equally a lubricant and retarder for the vta parts move. There are several other points that need this slowing down process and these also employ silicon oil. The unit of measurement in question was lubed with white lithium grease over the silicon oil. Luckily this unfortunate occurrence was in the very recent past and so there was no chemical decomposition yet.
Considering the white stuff contaminated the silicon oil, a general tear-downward of the unit had to exist performed. This process is roughly a days piece of work...
The moral of the story is this:
If you lot are going to lube a turntable, please look at its service manual and follow the lube guide lines. You can substitute an oil or a grease PROVIDING it is in the same family unit AND the onetime stuff is thoroughly removed and cleansed with booze at least. Exercise non put lubes anywhere else than where indicated on the lube nautical chart. Do not over lube. Equally you will come across in my restoration projects on my site, the lubes are non visible. Information technology is non considering I am stingy with Alvania or such, information technology is considering only the bodily contact surfaces need to be treated, Any spillage over this will only be a dirt magnet or become a sludge puddle which will hamper the works.
If you lot are lucky enough to see an untouched manufacturing plant lubed unit, you will be surprised at small quantity of lubes used. The first thought is that the changer need to be smothered.. Don't! The changer made it for thirty to 50 years in some cases with that thin amount.
In curt, if you tin run across the lube, information technology's too much!!
Take a wait at the pictorial of the 704 hither:

I hope the link works; if not go to my web page (the blue brawl beside PM on the left of here...) and open the Service tips then 704.

Question is what owners of newer Dual models, the service manuals for which don't incorporate any lubing infos anymore (and for which there also are no predeccessors with more elaborate service manuals...), should do - for example CS4xx chugalug-drive family unit model owners...

Wondering who treats his Dual turn tables similar that.... :oops:

Me? I'yard the guilty guy and lesson learned!

Simply guess what? Not many had the chance to meet in person with Dualcan merely I did.

What an endless recipient of Dual knowledge and I'yard then glad I did that mistake.

I'll post the experience I had with him but I must say, aside from his wonderful Dual noesis, what a admirer, actually.

Thanks Klaus for your tremendous contribution to this forum.

Best

How-do-you-do Manfred,
I looked at the mail service Steidinger manuals and tin can only shake my head.. While the Steidinger manuals have some glitches, sometimes in translation or simply from the steno pool, they are a gem as we, the erstwhile techs, are used to. When my partner and I were withal agents for B&O and Dual, the back up and parts were just outstanding.
With today's products, we are trained to just chuck it out as we practice with (insert> any printer/i-telephone/u-phone etc)...
I must say I was glad non to be associated with Dual once Thompson/Schneider took over. The products and service offered just didn't band my bell any more than, but I guess that is just the prejudiced view of an onetime geezer....
Regards,
ol' Geezer..

Hi Dual_Jean,
I am blushing crimson.... :oops: however you did not get my bill withal :mrgreen:
If I was you, I'd expect a tad....
It is such a joy to bring these old units back to life!
I am at present working on your 1019 and its smiles all the way.
With the revival of the vinyl era, hopefully many people can experience the pleasure of this medium. After so many years of clinical purity inherent in many CD's or the thin soup of MP3 whatsoever, the audio of vinyl really gets you going. Information technology is office of the aura that you lot will have to be engaged with this medium, fifty-fifty just to flip the record..
The involvement actually grabs you because y'all tin do so many things to the experience like changing carts, even different makes of styli.
I have a revox cd slinger and yes it plays great, merely I can't fool around with information technology as I can with dissimilar carts or unlike tracking forcefulness. I play all my vinyl wet, and I mean drenched! Try that with a cd....
Sure these are all micro adjustments and nosotros are probably pseudo-improving, simply we get involved! Howe involved tin one get with the new stuff---download from U-tube???
From a technical point of view, these machines are easily understood and don't rely on microscopic parts. It can be fun to get into the machinations of these things.
Since getting back into these machines, I am having a brawl! The next step is to become back into tape, of which I just acquired a TG28 in crude but achievable condition and a Woelke ME108, apiece of equipment I sorely missed from the one-time days. Three Dual tapes (TG 12/xv/28 and )several Cassettes (C830,901 and 939)await their turn!
These are the Duals that really turn my crank, mechanically speaking!
Regards,
one thousand

Klaus: Yup, it really is a pity that the more recent service manuals became and then minimalistic... *sigh*

What a trip downward memory lane!
This is how to properly pack a unit of measurement.
On picture 1537, my then independent Dual service agency, K&K electronics is listed in the Noresco Authorized Warranty Service Station pamphlet. I am sorry to say that I can no longer offer gratuitous warranty service withal...
What a hoot!

I had to delete the AK thread, too much problem with the images due to Microsoft screwing up Skydrive recently...

The trouble with ownership Duals (and vintage 1970's Beograms) that have been serviced is that the bloomin' things just work as well well!! My newly caused 601 is like this - flick the lever and the deck does the residuum fairly quietly (the 701 is almost silent when cycling). The 1972 vintage Beogram 3000 I also accept (don't know why, only I always admired it) is even worse;) Push the button and off it goes, although I did need to re-align the relay box to the main switch (Klaus volition know what I mean). The arm on the Beogram is a dainty and solid looking tube and the SP12 cartridge a classic, but the bearings are self contained (deliberate high-ish friction) and in that location's absolutely zilch to do once the idler/belt drive linkages are freed off :lol:

One day, I shall have to get a 1019. It'south so 'tactile' and the controls are really slick and shine, even compared to the 12** series. In the meantime, come back clonk, bang-twang Garrard Lab 80, all is forgiven :D :lol:
