Eliminate system hum


I have a tube system I have set up next to my TV but now have a pretty good hum. I have tried all the usual thing to get rid of it. Any suggestions other than moving it away from the TV? Why does the TV cause this with tube pieces and not with solidstate pieces?

NEVER use a cheater plug!!!!

That is extremely dangerous and does not provide a way for parasitic currents to ground. Believe me you do not want to be the path to ground!!!

The answer is to ground all equipment in the system to a common potential i.e. a single circuit or circuits that use a common ground.
