Default Searching for Marantz cd-50 schematics

I'm trying to resurrect an old Marantz cd-50, and then mod it for transport duty. Don't have the schematics yet though. Any kind soul here who could email me a scan of those?

Any modding tips that have proven to be particularly effective in this machine are of course also much appreciated!

Thanks, Wim

Wim,

Dont have the schematics (looking for CD60 schematics myself), but i got mine working. What is your problem, maybe we can help anyway.

Do you know the testmode? Hold three buttons and then switch the machine on. If you have the correct buttons (don't know the ones for this machine, but i'll have a try at home later) you get into servicemode. From there you can see what works and what does not.

Also opening the machine and having a look at what the transport is doing can reveal something.

Going to use mine to put in my own DAC later. As for upgrading this machine, you could go to non oversampling mode with resistor I/V without too much hassle. Search the net for info.

Greetings,
GuidoB

The first problem was that is skipped like crazy. Cleaning the lens didn't help, so faulting the laser I put it out of commission a year ago, and switched to a DVD player as temporary transport. Never really liked the DVD, and after reading that greasing the mechanism might help, even if it already appears to run smoothly, I gave that a try yesterday. It helped! The thing runs again, I'll give it a few days now to see if it holds up.

The remaining problem is sound quality. I'm using it as a transport into a half-modded Art DI/O, but although the Marantz is more musical and PRaTty than the DVD player, it's not very good at soundstaging and there's too much sibilance. So I thought I'd start off by replacing the 15-year old electrolytics, add some bitumen lining, and remove the entire D/A circuitry. (Though the non-OS idea sounds intriguing, I'll read up on that.)

But I'm not an electronics expert, I really need the schematic to see what's what...

I'm also looking for this one.

I own a Marantz CD62 that looks very similar.


If anybody knows where I can find the service manual for the CD50, CD62 or CD60...

thanks


Alex

Well, no luck on the board, but after a few calls today I found a place where I could order the CD-50 service manual for 20 euros. It's on its way, so if anyone else needs it I can probably get you some scans later on. (Might take a little while though, they told me it's a big document and I don't know when I have the time to scan it.)

Would you consider emailing me a scan of the service manual? If so, for how much?

Regards,
