Marantz CD43 / 53 / 63 Service Manual

[ALW]

I know there's a number of owners and tweakers of this player out there, I have the service manual for these players, and have scanned it into an Adobe PDF document.

It's 9.2Mb - if anyone wants a copy I'll place it on a website somewhere for download, let me know.

I also have some scans of the main PCB tracks, with the power supply traces highlighted (5V, +12V and -12V) for those that fancy tweaking and adding additional regulation, it makes it a lot easier to follow.

There's no mention of copyright anywhere within the manual, so it should be fine.

Andy.

At least I would appreciate it a lot. I have kind of copies, but those are not the most optimal quality....

Andy,

I would like to have the schematic. Someone wants to sell a 63SE in which the analogue outputs don't function. I could buy this and fix it with the help of the service manual.

Thanks a lot.

 

[wuffwaff]

yes, would be nice to have!

OK

Will post soon.

Yes, Andy, I want one too. Thank you.

Does anybody know which Philips items are similar to this players ?

Hi, I'd like to get a copy, as well -- I have a dead 53 on my hands I'd like to troubleshoot.

Thanks,

Got the manuals yesterday, looked them over, great work!!!!

Thanks a lot.

Link does not work, Netscape 4.72 says "The parameter is incorrect."

Anybody have a working link or link number?

Thanks

Eric

 

[lohk]

Thanks, Andy. Great work.
Some details are - hmm - quite interesting.

[wuffwaff]

I also can´t download

"plugin parameter incorrect"

[ergo]

wuffwaff and capslock, what if you try to select "save target as" from dropdown menu? I think the parameter error would more likely indicate a problem with acrobat plugin than a broken link...

Ergo

 

[ALW]

Link is fine

Sounds like netscape isn't!

Try Save as... - then view using Adobe Acrobat, then all will be fine.

Andy.

 

[hatasa]

Cool!!!

Thanks! I've got this.... they have the HDAM circuit completely.....

 

[capslock]

well, when I save the file to disk and try to open it later with Reader 4 or 5, it will tell me the file is corrupt.

Any other hints?

 

[guido]

Thanks, great stuff !!!!

By the way, i had a look at the 5 volts supply on the PCB, maybe i am going to make a new supply for the analog part of the DAC.
I probably use the +12 volt from the opamp supply.

But what i found on the schematic with the servo IC on it:
The supply for VREF with R124 is not comming from R122 but direct from the 7805. This also applies for R138, R148 and R132 near the TCA0372's above the servo. The supply coming from R122 is only used for the servo IC.

Nothing spectacular, but maybe a 'nice to know'.

Greetings,

Guido

You may find the following useful, it traces all (If I haven't missed any) of the 5V and +/- 12V rails through the PCB.

I suggest feeding the DAC analogue from a regulated supply is very worthwhile, but do the DAC oscillator supply first - it will make a bigger difference, the 5V supply rails are VERY noisy.

Andy.

Guido cont.

Here's the +12V and -12V supplies, and some of the RC.

How big is your downloaded file, it should be 9.2Mb or so.

I can only suggest a problem your end, since it's accesible to most who've tried.

It was created in Acrobat 4, so reader 4 or 5 will work fine.

Andy.
