Arcam A65 with EMI driving me nuts…

Greetings Forumites, I am looking for ideas how I can defeat right channel EMI in my integrated Arcam A65. It seems to only be in the right channel. The left channel is dead quiet. The EMI does not get louder as I turn up the volume which leads me to believe EMI is coming in after the power stage.

I do not think it is an issue with my speakers as the EMI is present whichever speaker I plug into to the right channel. Also, same problem when I plug in headphones. The right channel has the EMI.

Removing the CD, or other sound sources has no effect. The EMI is still there. It does seem to decrease if I touch the chassis, but not completely. Maybe, there is some grounding problem involved, but the grounding (green wire) and wiring looks tight to me inside the chassis.

I love the amp and don’t want to get rid of it, but this EMI is ruining my sound. I have the service manual and I am handy with a soldering iron. I can easily replace a few caps etc. if need be.

Many thanks.
