I have a ML39 and frustratingly the CD centering "puck" that sits on top of the spindle has broken. I've glued it back together once but now it is in bits. I've tried some places in the UK to get the part to no avail. I bought a part from one dealer for a stupid amount of money but it's the wrong part and slightly to tall meaning I've had to bodge it to make the top clamp/plate put enough pressure on the CD to let it spin up to speed.
Does anyone know where I can get hold of this part?
I'm going to try and attach an image but it might not work.
Follow Ups:
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
The piece of plastic itself
This image is the spindle with the offending piece of plastic still in place.
A case for 3d printing? I would have no clue how to make it happen but I did see some software that would allow you to take a photo or video of an object to get the 3d plan for printing.
Sorry Michael I can't help you with that part.I bought my No 39 about 20 years ago and promptly upgraded it to 390S through the Cornflake Shop off Tottenham Court Road who sent it to the then ML UK distributor. The 39 has an ancient DAC and you possibly deserve to treat yourself to a new CD player!
There's a 390S for sale at Ebay right now - https://www.ebay.co.uk/itm/26441992730. The biggest improvement over the 39 is the much better DAC, though even this is ancient technology compared with present day ones.
Asking £2500 but an offer of about £1500 may secure it.
Stone Audio in Poole had a 390S some while ago - worth a call maybe.
Better still, look at ML's latest CD to hit the shops later this year - the 5101. It plays CDs, SACDs, streams from Tidal, Qobuz, internet radio etc, is MQA compatible and has 2 Aux inputs as the 39 has. In fact everything (and more) that the 39 / 390S does apart from variable output. And all for less than the price of a new 39 over 20 years ago. £5500 list price. I'm seriously considering this and the new ML 5802 amplifier. Peter

I've seen that 390s and am tempted. But then I start to think whether it makes more sense to rip to FLAC ......
I'm really not sure what the best answer is.
and never look back.
Spending thousands on a new CDP makes no sense and unless the ML39 repair is easy and cheap I would junk it.... or sell it as is for donor parts.
I would buy an inexpensive replacement CDP like an entry to mid-level Marantz to hold him over while ripping ;-)
That is where my thinking is going. I can use the 39 as a DAC and get a Brennan B2 to rip and store the CDs and play it out via the 39 so keeping the sound I like. Alternatively, I have seen a second hand NAIM Unitiserv for a similar price.
I'm not sure what to do as it's all new to me.
The Brennan B2 looks good although it has a pretty non-hifi digital output - a combined optical and line out via a 3.5 mm socket. There are better ripping NAS units around that offer proper SPDIF coax and Toslink outputs.
Good idea on using your ML39 DAC if you can't get the transport section fixed. I used the DAC section from my Accuphase DP-65v CDP when I first started playing with computer based audio. The DP-65v doesn't spec like modern DACs (max sample rate, bit depth, DSD, etc) but it still sounds great today as your ML should.
Yes, it may be all new to you, so don't buy somehting in a hurry.
The Brennan B2 that you mention costs over $600! --- And you don't need it. If you've got a PC you can just buy some software like DBpoweramp and rip your CDs to Disk. https://www.dbpoweramp.com/Once you've got them to disk, moving them around to a NAS or other storage device is easy. Then you can choose from a wide variety of Music Streamers. Go cheap at first, until you understand it.. Don't just start throwing money at it.

Hi Michael - until you decide what to do you can at least take a look at the AA Trader. There's usually something here to at least consider buying.
A few years ago I bought a Rotel player in excellent condition as a backup and it still works perfect. Previous one-owner hardly used it.
Best wishes!
Could you use cd foam dots or the plastic/PVC spider centers sold for cd cases. Sometimes called rosettes. Perhaps as a temporary measure? I've seen them on Amazon. Cheap to try and usually in packs of 50 so you can experiment.

Nice idea but it needs to hold the centre of the CD and allow the magnet to engage with the top plate.
I finally found a pic of the transport and see the piece you are talking about. Looks like there is an upgrade part (link). Unless that's the replacement you already tried and didn't quite work.
Jonesy
"I know just enough to get into trouble. But not enough to get out of it."
Thanks for that. It's not what I have tried to use previously.I've taken a closer look. I bought a CDM9 transport with the hope I could just take the "puck" off there. But it is subtlety different. The metal ring in the CDM9, and the upgrade you found, is the magnet. In the ML 39 there appears to be a small magnet held in the central part of spindle around which the plastic centering disc fits over in an interference fit. The spidery thing I posted a picture off at the start of the thread.
When I took the centering disc off the CDM9 drive I had bought it turned out that the magnet in there was the opposite polarity to the one in the clamp mechanism. Rather than clamp, it pushed it away.
An age ago I have ripped my CDs to MP3 rather than FLAC so I could use a streamer with my NAS.
It's really frustrating having to junk a working ML all because of a 2 pence part. There is probably a bag of the damn things kicking around Madrigal somewhere and a bunch of people wondering what the hell they are for.

Michael - Have you tried contacting the present and previous UK distributors of ML equipment?
Copper itself isn't magnetic.
Jonesy
"I know just enough to get into trouble. But not enough to get out of it."
Not sure on replacement either. Hopefully not too tricky.
Besides the upgrade part, there are a lot of laser assemblies available which look like the include the exact part you have. But the cost is so cheap I can't tell for sure if it's just the laser, or includes the saucer table as well. Open to interpretation.

There's a ML 39 up for sale on Audiogon and the seller says it was fully refurbished by United Radio. I have no idea who they are and if they have the part.https://www.unitedradio.com/consumer-electronics/

I've dropped them an email. Fingers crossed.
