That you know Mark is having health issues.

It was not luvrockin who made that statement if you check again.

Gcecchetto was the poster

Thank you uberwaltz for saving me the clarification. As you are correct, it was not me

No worries

  My 1200 also used to hum off and on then I figured out it seemed to only hum when a curling iron was in use. I discovered that it was indeed the curling iron and now I know it  never hums unless the curling iron is on. Now that I know what it is it is no big deal.  It never seemed to degrade the sound much if any  at all .though. If not a curling iron it could be some other odd thing hooked up in your electrical system somewhere. I hope this may be the case and you can track down the cause.
