You might be able to adapt this project http://www.gamesx.com/wiki/doku.php?id=av:saturn_sp_difYou'll have to do some research on the DAC in the 503 to determine of it's compatible. My guess is that it being a later model player, the DAC is something off the shelf that can output s/pdif but was never implemented.

Interesting the block diagram includes optical, I think this explains why the Marantz lv510 ( I believe 503 clone) has optical out. seems like it could be fairly straight forward, I prefer coax but seems like extra work, and probably past my skills, optical would be good enough. Thanks for the info everyone, might give this a shot.

Well I got the second player today, unfortunately this player has issues, it was working ok until I reinserted the tray, now it will not respond to any commands, front display works and reads open, close etc, but mechanically nothing, no pickup movement, no loading motor, totally dead. I'm thinking power supply or maybe lose ribbon cable somewhere, not sure I will have to look at more later.
First player does function, however it will no longer play LDs, there is something in the video circuit when it reads the disc, it does play CDs ok though.
Edit: swapped power supplies between players and no change, problem must lie elsewhere...

I got second player functioning better, and was able to get it to load an LD, unfortunately it will not play either LD or CD, LD does try to spin but spins down immediately, CD will not spin it all, when trying to play CD pickup moves all the way forward, then gets stuck and will not move back unless gears are turned manually, also in LD mode sometimes player will stop functioning until pickup is returned to rest position.
First player has only LD play issue,but also it has loading issues, the pickup assembly will not lift fully by itself, also tray will get stuck sometimes when closing. Grip ring and Belt were replaced on first player.
I will try and make a video to show some of the issues with the players and yes both are 503s
