Subject:mains hum

Hello All
Happy New Year
Could anyone help me with this problem?
If I crank up my amps over 25% volume I get bad mains hum.My gear is in a spare room in my house, and as I don't gig anymore I don' get much chance to put my foot down.
But when the wife is out I have a chance to play loud.This gets the best out of the V K 7 IMO.But the mains hum coming from the amps drives me mad.It can't be heard on heavy parts but can on soft or mellow parts of a tune.Changing the volume on the keyboards does not cure the hum.Only turning down the amps helps.
My gear:-Korg i 30 HD,Roland V K 7,into Sampson mixer,then into 2X100 Watt Torque Amps.Not very sophisticated I know,but all
I need!.Can put the V K through my rotary speaker,but need the amps for the Korg.
We are 240volts 50hz in the U.K.
Pete
