Philips CD492 Schematic

scaramoucheii · 4th July 2011, 02:44 AM

Hi All

Anybody out there have a schematic for the old Philips CD492

I have installed Burson Discreet op amps, clok and regulator, and replaced all the diodes with Schoktee, but want to do the cap replacement now and would like to know what caps are doing what so that I can spend the money in the right places.

regards

Can you attach a small photo of the mainboard?

I am pretty sure it is the same board as many Philips/Marantz boards.

Here is the photo ,

I know that it is the same as a Magnavox CDP492, as sold in North America.

Any advise on what coupling capacitors and powersupply capacitors are critical would be appreciated.

Are you sure the Philips model number is cd492 ?

I think it is a CD 482

It's a CD 492 ...

As per the face plate,

I know it was also sold as a Magnavox CDP492 in North America.

looking around the web and, here on DIYaudio, I see quite a few similer units, but cannot seem to find a schematic to base mods on.

I have looked at Hollowman's thread, I'll PM him and see if he has any thing to add here.
