Dual 1019 noise level

[Nvrpcktp]

Hello, I recently bought a Dual 1019 from a guy who told me he completely serviced it. I must say I'm in love with this machine, but since it's my first idler TT, well, I'm not sure what to expect. So I'm uploading this little audio clip for you to listen and tell me if the mechanical noise can be reduced or if it's the best I can get from a 50-years old machine.

Thanks

I haven't listened to the clip, but a properly serviced 1019 should be virtually free from noise.

I've owned two different 1019s and both were very quiet. Based on your clip I would check the platter bearing and make sure it's straight and well lubricated. One problem with the 1019 and many other changers is that you can't easily adjust vertical tracking angle and the 1019 arm is going to give best VTA on the third record. You might want to put a cork mat atop the stock mat to bring the VTA closer to optimum. Otherwise, try shimming the cartridge.

I cannot hear anything with these laptop speakers. But I will tell you that I have seen many 1019 and 1009 that are super-quiet, and a few with rotational noise that in all cases was from a poorly-worn or damaged brass bushing on the platter. That damage was obviously caused by a damaged platter support spindle, which is a harder metal than the bushing. Stuff like that does happen, but not often.

Motors with dry bearings can generate unwelcome noise

Pretty straight forward to remove, open up, clean and re-lube too

In fact I've just done mine

Sounds reasonably quiet to me. My 1019 is also a tiny bit noisy even though I've cleaned and lubed things.
There is a bearing with multiple balls supporting the platter. IMO this part is not the quietest mechanism but it is necessary for the hollow spindle with the changer mechanism.

Your 50 year old machine can do better.

OK, thanks a lot for your advices. I don't think I can make a better job with the platter bearing, but I can tell the motor wasn't open a all, and it may be needing a lubrication: there is a hum that's way more present while playing 180g LP's (not the one in the clip). About the cork slipmat. I may try to cut it myself, how tick should it be? Can I cover it with a second cloth mat to avoid residual debris?

Could not hear any noise. Never had noise issues on the 1009/1019 that have crossed my bench. They are pretty quiet. Is it out of its base? When servicing them, I have the base removed and its sitting on the bench. The motor is touching my bench. Once put back into the base, it's quiet. Just a thought.

My ears are a bit compromised right now (ruptured eardrum ) but I tried and could not hear any noise.

Hum, if present, is unlikely a motor issue but more of a grounding or bad contact problem. Dual sleds and muting contacts often need some attention and fixing that might help.

What you describe continues to point a finger at the motor, especially if you don't believe it's had any attention in it's 50 year life.

I had a "hum" on a Dual 1219 which was pinned down to and addressed by a motor strip down, clean and re-lube.

In your case the fact that thicker/heavier vinyl appears to increase the noise level does also indicate motor loading as the potential source.
