I just installed a ca. 1980's B&K ST140 to my Outlaw 1050 and noticed that when my TV is on there is a hum more noticable than before. It is coming from the TV and also from the main speakers.
I previously had a Dynaco 400 power amp and didn't notice this.
I live in a house built in the 50's w/o a true ground. Will a power conditioner help? If so any recommendations?
