RE: ML 39 spindle part

I am astonished and the mystery of why it didn't fit solved.

Eventually I identified that the lazer assembly is a VAU 1254 cd-pro 2. Made by Philips.

This led me to a North American distributor of such assemblies called Enco. On their website https://encosystems.net/ they sell a replacement part called Standard CD Pro Centering Hub which is the one I have and is a direct replacement for the "spider type" which is the image in my first post.

I dropped Enco an enquiry about why it might not fit and overnight a nice guy came back and told me that while the assembly around the spindle looks bare it probably isn't. There will be a thin piece of plastic there and while the Enco supplied centering hub looks like it fits inside the rim it doesn't and leaves it sitting too high. Take it off.

So I opened up the ML39 again and started poking around with some tweezers and to my surprise a thin piece of plastic around the spindle lifted up. After removing it and putting the replacement centering hub back on it works perfectly.

Thank you everyone who took time to respond to my plight.

The attached image is the bare spindle. The next follow up will show the offending piece of plastic in place on the spindle.

BTW I will be ripping to FLAC

Hi, thanks for sharing your problem with ML39. It looks like all we have same issue.
My centring cone/turntable hub is broken a parts as well.
I would be appreciate if you are able to measure replacement hub. I have access to 3d printer and I can try make one, maybe even more stable one.
Thanks!!!

  Sorry but I don't have a micrometer to measure the part. I realise that because you have a 3D printer it probably isn't too much of a hassle to repeatedly make a part until you hit on the perfect size but that is the fundamental problem. It needs to be the perfect size in all dimensions for it to fit to the motor spindle itself and then the fit to the CD. The CD is held on the spindle "puck" by a light but nevertheless firm interference fit. The piece of plastic that I managed to leave on the spindle when I first fitted the replacement part was very thin. It was only 1-2mm thick which was enough to make the new "puck" sit very slightly too high which meant the mechanism was unable to clamp the CD and the ML39 would just say it couldn't read the CD. Even if it had managed to clamp it wouldn't have read the CD as it would have been at the wrong height for the laser.
  
  I would seriously recommend just buying the $35 part from encosystems.net
  
  I also found a European supplier akustik-perfect.de

Well done Michael. I'm pleased you persevered and managed to find the part. Now you have an excellent CD player which, if you rip your discs to FLAC, will give you many more years of occasional use. Peter

This image is the spindle with the offending piece of plastic still in place.
