Thanks for the info Barry,
I found the following instructions and thought they might be useful to others. Ive carried out the modification using the RF board from the CLD-515 but I've yet to test it.
Fingers crossed!! I'll keep you posted.
Specific Instructions for Individual Players
Pioneer CLD-2950
The following instructions come courtesy of R Larsson. The Pioneer CLD-2950 is a dual-standard (NTSC/PAL) player for the European market, very popular and probably the best of its kind available.
Remove the top cover by loosening seven screws (two on each side and three on the back).
With the front of the player pointing towards you, remove the large board on the right side of the player by unscrewing four screws, and thereby "folding" the board out to the right, and placing it in the three slots designed to hold the board during service.
The narrow board you now see is the AFMB board (Analog FM sound board). The big chip on it is the "FM-demodulator and CX-decoding" HA12127ANT. Four of the five taps are done on this board, and you have to remove it completely from the player. Loosen two screws and one clip, then pull out the four jacks. You can now take the board out.
Now place the AFMB-board so you have three jacks on the right side, and one on the left side. You can install the home made AC-3/RF-board.
Solder the wire for +5V to jumper W187 on the left side of the AFMB-board. At the same place you'll find a marking for C175 which is not mounted. Place the wire for -5V in the hole for C175's negative pin (marked with a square), and solder it on the print side of the board. Similarly, solder the wire for GND to C175's positive pin. The wire for the AFM RF-signal (as short as possible!) is solded to jumper W355, on the right side of the board.
Fasten your home made board to the AFMB-board some way (double-sided sticky tabs should suffice).
Location of the Mute-signal
On the edge of the main board (the one at the bottom of the player), above IC201, marked PULSEFLOW (D/A converter) you'll find a jumper marked W206 and MUTE. You'll need to solder the mute-signal wire to this jumper, but be careful not to touch any other wires with your iron during this operation.
Finally, mount the RCA jack, the coax, C2, and after putting the boards back in place you're ready to test you're glorious new creation.
