Marantz CD 65II problem

[ubaldojhp]

Hello, I have a Marantz 65 II with a problem. When you turn it on it makes a mechanical noise in the tray, I don't give it much importance but it is there. The main problem is when playing. At the second song or so the tracks fast forward to the end and stop. It does this in the first 10 minutes or so after turning it on, then I put it on and it plays the record correctly at once. It's like it will need to warm up before it works well. I have also observed that it gets quite hot for a CD. When you put your hand on the case you notice a lot of heat. Basically that's it, let's see if someone can guide me. Thank you

I would first suspect that the grease in the laser carriage mechanism has dried up. This would explain the skipping and the noise when you turn it on, as the system struggles to reset itself. The heat could be normal and could be coming from the transformer, but I'm not sure, although it would also explain a) why the grease has dried up, and b) why everything works a little better once the grease has warmed up a bit.

If not the grease, it might be that one of the drive belts (if there are any) need replacing.

Old CD players often develop these small faults. The tray on my 1990s Philips, for example, won't open on the first presses of the eject button - it always takes at least 3 goes. I suspect it's a dried out electrolytic capacitor but I haven't bothered to find out which as it's not yet a big problem.

Thanks Ropie, I'll check what you told me. It really has its logic

Yes, looks like leakage. Definitely replace that one if you can. Will it solve your mechanism problem? I'm not sure..

I don't know if you solved the problem already but I recommend to change all the capacitors from the power supply.

This player is very good and I recommend few upgrades to transform it an excellent player:
 - put it in no-oversampling mode;
 - change the TDA1541 decoupling capacitors;
 - replace the output stage with a tube output - the change is huge.

Thanks Vlad. I have to pick the capacitor this week in my local store

This caüacitor is not leaking!. What you see on the pic is some glue fixing the tall cap and avoid breaking of leads due to vibration (e.g. during transport in a plane).
However, this does not mean that capacitors of such age are not faulty - the most prominent failure is that they dry out and lose capactance and/or getting high internal resistance.
