I have a 10 years old Kelvin labs A type amplifier. Lately it has humming noice after I moved it around. I tried to put on the ground wire, but it doesn't help. I unplug all the RCA input then the low noice gets even louder. When I lay my hand on the case, it reduce a bit. The right channel also make more noice than left channel, as I switched the speaker. Does anyone know how did it happen and how to fix it.

Your amp is not that old, but its electrolytic filter capacitors in its power supply section may need replacement.

It's also possible that some grounding wire inside has a loose connection.
