Thanks for the warnings. I am recalling a story I heard some years ago about one of the former members of the Yard Birds. He electrocuted himself while tuning his electric guitar. I assume his guitar amp wasn't properly grounded.
The hum is definately in my amp since it remains when I disconnect my CDP. Since it's an integrated, there are not separate power plugs for the preamp and amp. Besides, the preamp is passive.
I have seen several products designed to block RFI and EMI, like the Stillpoints ERS cloth ($20 at Music Direct). Would these products be of any help? If not, the hum is minor enough that I can live with it.
