Damn, I kind of wish I already knew that. It's now plugged into the line
input at the back.
This is a little OT but I think something might have happened to the
amplifier.
When I listen to the output on my computer the left channel is
completely distorted, when I listen on the headphone socket on the amplifier
it sounds fine.. bearing in mind that this is an Technics SIJ-500 amp that I
found on the side of the road, does anyone know if this is fixable?
