Amplifier of DVD90 (my):
TDA7561 (datasheet in attachment)

On PIN 11,12,14,15 is a 0.22uF capacitor connected, on the other side of the capacitor (preamp side) solder a shielded wire, where GND goes on PIN13.
(I took two of the signals from the top side of the board 2 from the bottom.)

You need a preamp

For remote my CD30MP3 PIN13 was suitable, but dvd90 has a +5V signal, so I took the I2C information from the original amp (mute info/standby).

PCB express PCB layout in attachment (it is prepared for single or dual power supply, in case of single, the GND = V- and please take care also that the right Zener diode is placed (12V))

(Who thinks that DVD90 has a better sound: Not, never, maybe the loudspeakers, CD 30 has the same amp IC:

and I have to say, that after my upgrade, the DVD90 has less sensitivity then my old CD30MP3)
