Hum from amp - should I worry?

is the amp itself humming or do u hear the hum through your speaks? if the former, the hum is likely from the transformer. this is not normal & will likely not b fixed with a power conditioner.

It is the amp itself for certain - not the speakers. I called Meridian and they said something about the transformer coil causing it, but that it wouldn't effect my performance. The hum has actually died down to almost nothing since I made this post, but then again, I'm still concerned. So far, no effect on performance. We'll see. Thanks for your feedback.

I have a Belles 150 A hot Rod, that has a transformer that hums once in a will. According to David Belles this is caused by to much voltage or to little in the power service to my house. I do not know if this is true, but the amp has been dead quite for weeks.
