The sound when connected to RF was fine but through the phonos it does not sound right as in the volume is low and only 1 channel is working but both phonos are working but both are outputting the same i.e no stereo which means half the sound is missing.
What could the problem be?
Phono cable is good as its the same one i use on the A1200
Probably capacitors. I don't have a schematic for a 600 but there are likely a half dozen or so in the audio circuit.
