Dual 1019 Rescue Mission

Super Member
Well, I’m sure we’ve all done it. We get something neat, we sell it for something else, we miss it dearly, and months or years later, we let our id get ahold of us and we take an ill-advised gamble to get another. Tale as old as this website, right?

Well, as you can tell, I missed my Dual 1019 within a few months of selling my last one, and even in spite of having a 1229 and a Pioneer PL-L1000, frankly I missed the little bastard! There’s just something really...nice about those slider switches, and the compact chassis, that speaks to me for some bizarre reason. Plus, who doesn’t love a 1019? So, I headed over to ePray, and took a gamble on a beater, loose chassis. No cart, no headshell, no plinth, and broken teeth on the platter. Doesn’t that just sound SO enticing? I’m a sucker for a rescue, and there weren’t any available in my area, so screw it. And to make it even more exciting, the seller gave every red flag in the book. When I PM’d them detailed instructions and a video on how to package a turntable so that it could have some semblance of survival, they curtly said that they “added an extra layer of bubble wrap” just for me. Cue internal screaming.

Well, miraculously, it arrived about as intact as it was in the listing, despite literally being wrapped in bubble wrap and insulated with old flat rate mailers, in a cut down moving crate. And true to the seller’s word, the teeth on the bottom of the platter were sheared off somehow. I haven’t had a chance to go through it yet, but the gear itself looks OK. Weird.

The platter is definitely screwed, though. I know Dual platters can be a little warped, but this is...bad.

Luckily, I just so happen to have a spare 1019 platter laying around, after a failed attempt at fixing a slightly warped platter on my last one. Unfortunately, it doesn’t have a mat. Guess I’ll have to find some way to remove the mat from the old platter without bending the delicate metal trim ring, or buy me a cork mat and cut that down to size. Fortunately, this one seems to spin fairly true, but I’ll be sure to clean and re-oil it.

Also, the power cord. Hard nope on that one. Not even going to plug that sucker in.

Lastly, the headshell is a bit...loose on the tonearm. Gee, wonder how THAT could have happened. Thankfully it looks intact, and not bent or broken, and the arm moves freely, and anti skating is doing it’s thing. The rest will just be fairly typical Dual 1019 stuff-cleaning out the gorilla snot, applying the CORRECT lubricants where they need to go (learned that one). Already ordered a new headshell and sexy United Audio plinth, so I’ll tend to all that while those are on the way.

Stay tuned, y’all!

Wow, you're in for some fun ;-)!
... seriously: kudos for taking that poor thing under your wings.
 
How does the platter get warped ?

I have no clue, honestly. My 1229 and my last 1019 have a millimeter or two of warp if we’re being generous, but this is just..completely dished and cracked to hell. I can’t even fathom how it got this way. Guess it was a Monday job that got dropped or something?

Cleaned up nicely underneath. Looked like some ijit sprayed WD40 or something all underneath it in order to rejuvenate the old grease, causing it all to harden and left this weird white residue all over the bottom.

The cam gear was especially heinous, and filled with this dreadful black sludge and covered in what I hope was glitter, but was probably parts of the original platter gear. Yikes!

I get zero resistance when I turn the platter by hand and all automatic functions are smooth and silent, but I’ll test it under power once I clean out the motor and sort out that dreadful power cord. The new plinth and head shell will be here on Thursday!
 
I'm getting one of these working myself right now. My first Dual resto. I thought mine was a bit of a problem child - but I'm now thinking you are a braver man than me LOL. Nice job so far!

First example of crapalloy rot I've seen on a turntable platter, all too common in single motor Roberts/Akai tape transports and numerous other units with crapalloy parts. I think of it as a "when, not if" event with this stuff.
 
That actually might work.
You have an early unit. The two motor bushings each have a ring of foam to retain oil. The foam has long turned to dust. This makes a short clean and oil a project.

I'm working on a 1019 now and oiling the motor is on my to-do list. If the foam is shot is there a substitute? Thanks!
 
You need to drill out the rivets retaining each bushing and make an oil wick out of a bit of wool felt or even just plain wool. No synthetics. Real wool.
 
Thanks- Here is a pic of my motor - not sure if you can tell if it's an early version or not. (sorry don't mean to derail the thread)

OK, so the new platter mat and some extra cleaning supplies should be here tomorrow. The new headshell oughta arrive by Thursday, and the plinth and spindle should get here by the 5th. Hopefully by then, it'll be all sorted out and ready to go!

I opted to buy a cheap cork mat that I can cut down, instead of trying to rescue the original rubber/metal mat off of the old, warped/cracked platter. I'm not feeling cocky enough to attempt that without further bending the thin metal ring, and besides, the ad told me that this cork mat is more "audiophile" (*wink*).
 
Got brace and plugged her in. Predictably, the motor was in a sorry state and the platter could barely get up to speed, so I took it apart, cleaned it all out, and gave it some much needed oil. Seriously, the thing was bone dry.

Didn’t have the tools handy to drill out the rivets and replace the foam bushings, but luckily these appeared to be pretty ok. Project for another day, that is.

While I was at it, I gave the idler a good sanding, and cleaned the old oil off the main shaft and put a few drops of chainsaw oil on there. BIG improvement! It now gets up to speed fairly quick and seems fairly steady. Spin-down time is about a minute from 33 RPM, which is pretty dang good I reckon. Recorded about .18% wow and flutter on the RPM app in spite of the flat idler, which I must stress is not an accurate means of measuring wow and flutter. For comparison, my 1229 measures 0.16%, and my Pioneer PL-L1000 measures 0.11% using the same app. So I’ll go ahead and give it a clean bill of health!

The foam oil wicks are long-gone.
With all the work you have put into it, take apart the darn motor.
Either all of your turntables are way out of spec or your app is. Your wow/flutter is twice or more of what it should be.
