Screw on a 1219 tonearm

Post by babadockia » 19 Nov 2019 09:42

Hello everybody! How all of you are doing today?
I have a question regarding the screw in the picture at the back of the tonearm on a 1219: what does it do?

It restricts how high the tonearm can be raised.

The service manuals aren't always easy to understand, but it definitely helps if you read several different ones, as *broadly speaking,* many Duals are so similar operationally (but obviously with styling and material changes over the decades). I've sometimes found better descriptions of certain fine tuning operations in alternative manuals...

Please, could you give me an example where the need, function or behaviour of this screw is better explained?
Thank you in advance

Damn my words - they'll eat me one day...

The nearest I can find on a ten minute trawl is on the 1229Q service manual available here in the library. The numbered part is #79 in the exploded diagram and referred to in the text on page 9 and corresponding diagram 13, which only shows how the tonearm max height should look relevant to the tonearm rest, which is adjusted with set screw #79. I'm sure others will find better descriptions somewhere.

Similar is in the 1219 service - part #54 is the max height adjusting screw and fig 11 showing where the arm should be once this is set.

My own advice is to set the max height slightly too high, carefully carry out the description for tonearm lift height on 'auto' and then adjust the max height screw for a smidge of free movement as explained, and only setting the cueing height last... Does this make any sense or is it help to you?

Of course it is of a great help because I was secretely hoping to be some kind of a hidden possibility for VTA adjustment. I mean, Lenco had it on their crappy tonearm, but not Dual on this almost perfect one?
Sorry, I have a bad tooth against Lenco, it is so infuriating inferior to 1219 but nobody sees that. Sorry for the flame

According to Rega, VTA as in tonearm height adjustment isn't so important as all records differ in thickness slightly and you can fine tune VTA with 1/10g tracking force differences. My experience is that some audiophiles get totally anal about things like this, as well as with setting the overhang in the carrier.

To continue respectfully, the kind of cartridge that would normally be used in a 1219 isn't going to be *so* sensitive to VTA (would you be using something like an AT95ML/SH or 540 or Ortofon 2M Bronze?).

No idea what cartridge you wish to use in this deck, but I'd suggest to fit and forget. I can try to help further if you tell me what you'd like to use in it.

So far I have the one that came with it, DM 103 (shure m91, if I understood corectly) and a V15 type III LM with a hyper ellypse stylus (not enough funds

Thank you kindly for the reply. So far, it has a DM 103 with a shibata stylus (shure m91, if I understand correctly) and in the very short future a V15 Type III with a hyper ellipse stylus (not enough founds for an SAS)
