Dual 1019 Multi Record Spindle Conversion

Good day All,

I have picked up a my first ever Dual; a 1019 with a multi record spindle. Never been a fan of dropping records (do not want to start that discussion in this thread) and want to know if it is possible to convert to a single play spindle? Once I receive some feedback, the direction of the refurbish will be set. Thanks in advance for the response.

Great table, probably my favorite Dual. The service manual will help a lot and it used to be easy to get for free from Vinyl Engine, but so many people downloaded manuals and then printed and sold them on the internet that the owner restricted access, and if you aren't already a member, you will have to find another source.
You remove the multiplay spindle by push down lightly and turning it a bit, at which point it can be lifted up. If the spindle works, there are people out there (with either a different view of listening pleasure than you have, or simply want to have all the accessories) who want it.
The correct single play spindle looks very much like the one used on other later Duals, with a wide base that presses onto the platter bearing - I'm uncertain whether they are the same. Or you can use a standard changer single play spindle, which looks like a long pill capsule. Or you can use a pencil stub - really. We did this all the time back in the 70s, and we hadn't invented it - it goes back a long ways.
 
Thanks for the swift response Nat. My thoughts are to convert to a single play, keep the spindle for when I pass it forward, and refurbish mechanically and electrically as needed to get it back to showroom performance. I've his a brick wall at VE, not accepting new subscribers. A shame some ruin it for the many. That said, I'll scour the net for a copy of the service manual which I'll need regardless of my conversion.

I've been able to easily remove the spindle, it's fully functional, drops records, and I'll retain. If I understand correctly, just need to source a single record replacement spindle and as a last resort use resort to a pencil... ;) Seriously, any precautions on the replacement so as not to damage the receiving mechanism? Does the replacement need to be keyed?

The single spindle lightly hand presses into the platter and rotates with the platter, not into the stationary bearing hole like the stacking spindle does.

Tozco shows the item in question, and he is, of course, right that the wider section is slightly compressed into the platter hole, not onto the main bearing. I was specifying location, not which part the piece mounts on.
When you say 'convert to single play', do you mean simply using it with the single spindle as a single play automatic, or do you mean removing all the mechanism down below and having it completely manual? I ask because these were always usable as single play automatics - the spindle is the only difference between changer and single play - and I am not sure if it is possible to remove just the changer part of the mechanism and still have single play. I don't think so, and I think you would find no benefit at all - you wouldn't be removing enough to end any possible vibrations of the mechanism from affecting the sound (assuming they actually do).
What might be worth doing is building a stouter plinth - the particle board many plinths used for the top sags badly over time. And I can imagine that using a massive plinth and tightening down on the suspension might have the same effect on Duals that it has on other turntables, minimizing both the mechanical noise of the motor/bearing and acoustical feedback.
 
Tozco, a picture is worth a thousand words and that details is greatly appreciated. Is the example an aftermarket replacement or original equipment? I am optimistic the former so the search is a bit easier.

Nat, not building a Frankenstein... just want to remove the multi-drop spindle with a single record spindle. The unit came with a wooden plinth, in great shape too boot.

It;s also possible to convert the long stacking spindle to single play by removing the "guts". The white cap comes off. Then, rotate the inside "lock" counterclockwise until it releases and then the internal parts will come out. Records can then be slid down the spindle without interference. Save the internal parts and you can reassemble later, if desired.

That seems a labor intensive alternative to simply buying the single play spindle. And in my house, those saved internal parts will be underfoot until a month before I decide I need them, at which point they will have disappeared completely.
That's a very nice 1019 you have there, and I see that your plinth seems to have a substantial top and no likelihood of ever sagging.
 
Very nice table. I have owned one since 1967. Bought new while in college. Overhauled once by FixMyDual in Iowa.
 
Great feedback all. Now comes the search for a replacement spindle. Should you have suggestions on where to find, outside of "the-bay", I am all ears.

Thanks,
Mr C

Wonderful deck. I have two 1019s, need to get one out! Btw I used to have a 1019sk that was a really nice stacker.
 
Does anyone know if the later Duals used the same size single play spindle as the 1019?
 
The ones I have look identical to the one in post #4 above and seem to fit a few different models.
 
I asked because I might have one, but ESP seems to have taken care of it. Nice!

I didn't say it was the best possible solution. I just mentioned it as a possibility in case he wanted a usable spindle immediately.. It is not labor intensive. It's easy to do.

At the risk of stating the obvious, what a fantastic forum! The wealth of information and generosity of the community is invaluable and indefinable. I appreciate the support, encouragement, and comradery from fellow audio enthusiasts. Special thank you to ESP... I will make good use of your kindness. Will post the end result when completed.

Best...
