Speaker Hum

I just moved into a new (to me, actually built in the mid 60s) house where no matter which outlet I use I get an audible hum through the speakers when the volume of the integrated amp is pushed past 50%. Would any power conditioners improve or eliminate this severe of a problem? Any thoughts would be appreciated!

Sounds like cable TV.

Yes same hum regardless of input. Also I thought of the tv so I unplugged everything except the amp. With just the amp plugged in the speakers hum starting at just over 50% volume and get the hum gets pretty loud as you get near max volume.

You sure it's not either cable TV as @fuzztone suggested, or an internet (Wi-Fi) modem nearby?

I do have both a modem and tv nearby but all of those outlets are plugged into one dedicated strip. So I unplugged the strip while testing the hum. The only things I left plugged in were the amplifier and the speakers, which have powered subwoofers. My other components - turntable, phono stage, streamer, etc. were plugged in but powered off. Maybe I need to disconnect them all from the amp as well or that doesn't make any sense?
