Hello,
I just picked up a Marantz SM500DC Amplifier, SC500 Preamp, SF500 Tuner, and EQ-20 Graphic Equalizer.Got it home and hooked it up, and everything appears to be operational. One issue I have noticed is that the left channel will fade a bit only when using the Aux input from the pre-amp. When using the tuner input I get clear sound from both channels. Is this just a pot and switch cleaning issue? Or something further? Thanks
Jake
