For 80 meters a type 77 material torroid would be the best.  Get a medium
sized one and put as many turns of your speaker wires around it as you can.
The best place to put it is likely near the speakers.

I have one of these on mine and it takes the interference out completely.
My computer in my shack has speakers in the monitor and they were horrible
until I put the torroid on.  Now, I get no RF problems at all with them.
