Hi all
I tried to find a thread in answer to my question but couldn’t so here goes. Why is the (what I understand to be an) signal earth lift 10R resistor in parallel with 0.1 uF cap (installed from negative speaker post to chassis earth post) fitted to only one side/one channel of the amp (WD88VA). I naturally thought what was good for the right channel would be good for the left as well

Thanks in advance
Phil.
