My Hot Stuff makes a strange whining buzz which changes pitch as more/less lights come on.. At first I thought that it was coming from the speaker and it is.
But the noise also comes from the reel motors and the PSU. Interestingly, if I touch/move the reels, the noise changes (it gets louder).
Is this normal? I was told that it was, but last night I was in a pub (which was fairly loud) and put my ear against the speaker and heard nothing.
My machine doens't make a feint noise, but a racket which can easily be heard from 10 ft away.
Ive had a few machines, and they have all made a noise, some worse than others. I think you notice it more when its in your own house, no background pub noise to drown it out!
