I have an HP-100 that had a wicked hum, and I was first advised to float the grounds. It worked wonders - hum disappeared whether I had the blue light on or off. The second suggestion I was given was to check interconnects.
Hovland HP100 hum?
I have a Hovland pre and VTL ST150 amp. Connected to the Alto Utopia Be speakers through synergistic research cables all around. The hum from the Hovland is too much. I can hear it from my listening position. I am using cheater power plugs, so I dont think it is the earth connection.
Any advice or ideas? I think I read about the Hovland hum in some of the reviews.
Thanks.--Michael
