Marantz CD63 loading discs off-centre and wobbly

[dwjames]

Hi All,
I've just got a fairly special modded Marantz CD63 CD player, but it's not playing some discs unless I mount them off to one side in the tray.
With the case off I can see that evne if the discs do work and read ok, they're really wobbling around as they spin.
It's as though the disc isn't sat onto the central cone properly I guess.
I'm not sure if it's had a bash in the post or if the mechanism's faulty.

Are there any alignment adjustments I can have a play with or is there anything I should check?

Here's a quick video that shows the wobble

And here's one that shows how sometimes it works, sometimes not

Any ideas?
cheers,

I've just checked back and it seems this player has just had a new Philips VAIM 1201 laser unit fitted.
I guess maybe the original M12.1 top clamp is still in place and isn't compatible?

If that's the case, can I just buy one of these and swap them over?

This appears to be down to a faulty mechanism with the CD cone seat not sitting square onto the spindle. I'm changing it out for a new one.

Did you manage to do the cone seat project on your cdp? Do you have any pics to post of the process you followed?

Cone seat project?
No, I found the plastic cone was sat at a slight angle on the spindle so it was never going to run true. It was supposed to be new, so presumable a sign of cheap and crappy manufacturing. I just swapped it all out and all is well now.
