Krell 400xi - Distortion in right channel !


Hi
I noticed my krell 400xi had distortion clicking sound in right channel even then amp in idle mode. Eliminated all other suspects like cables, source, speakers. etc. As long as power plug in, the floor hum distortion is appear in right channel , in turn off mode or turn on mode. If anyone know anything please help.

If you've eliminated any other source of the sound then you may want to have a local tech take a look. parts that fail horribly can cause more damage on the way out.
