Ok the psu is mains voltage and takes power direct from the blue and brown wires entering your cd player. But, it looks like it has 3 points on the grey screw fit connector block which means it could be expecting a ground wire/earth, which your cd player doesn't have. Flip the PSU over and see if there are only two or three sets of tracks running from the psu connector block. I think there's only two, if so splice in one wire from the blue and one from the brown into the connector, any way round will do it's AC. That said, i can't see where the power comes out of the PSU board, so take a pic of the under side first please.
The superclock board looks like it takes DC from the red wire coming from under the main pcb(power +) and then connects the longer wire to a gnd point where it's soldered to the main cd player pcb. So those two points on the superclock are power+ and gnd, just desolder them and connect them the correct way round to the output pins on the superclock psu pcb. You might need to leave the existing ground wire to the main pcb in place, but I suspect the shield on the coax that carries the clock signal is also effectively power-gnd.
Lets see both ends and the underside of the psu and we can work it out.
and as always it's mains voltage, so if you don't know what you're doing at all, don't do it.
