In my case with a similar setup, i use cheater plugs on the mono blocks and an FM tuner... cures all hum. Good luck with the headache. You will find the solution. Bob

This morning the hum level is back up to the previous annoying levels. CJ told me to get some cheater plugs and try one first on the GAT to see if this eliminates the hum. If not, put another one on one monoblock, see if this kills hum. If not, will need another cheater plug on the CD player. Long term I need to get an electrician to wire a dedicated 15-20 amp circuit for the stereo.

On to the hardware store tomorrow. Thanks Bob! Are you still enjoying the LP 140's or have you been tempted to move up to the ART's with good demo prices popping up periodically?
