Nice cars! There must be some strange connections between modding cd players and fast cars/bikes. To much money? ;-) Btw, I drive a Smart Roadster Brabus (remapped). Small engine, but it's light and loves corners like anything.

On topic: tnks Allan for paving the path for me ;-) What's the point of connecting the clock out to the decoder leaving all the components (cap + resistor) in place? Didn't hear huge improvements. Used a standard coax cable, does that matter?

Did that too first time, didn't work for me either. If I've read the few last pages correctly, you'll be needing the c521 cap and u193 resistor if you have the mk2.

Quote:
In the MKII, RD14 is a 100r in the space of u193 and C521 is a 10pF in the space near the the DAC marked "RD14 or C521" You need both components between the clock and decoder.
Please correct me when I'm wrong.

Just studied the schematic cut u193 and rd14/c521 and feed pin 13 on decoder that seems logical to me removing u193 and rd14/c521 .

ps just about to try wish me luck

Pin 4 on the dac 16.934mhz output to pin 13 on decoder should do it.

I've added an overview / guide for the 63 covering the important areas to my site. I have left out things like resistors and poly caps etc as Ray mentions all this.

Looking through your mods, for the bit clock it says take a 4.233MHz signal from the DAC. Where? I can't see one listed in the SM. I can see one on pin 29 (CLA) of the decoder though.
