My SW10-II was new in 1994, and I'm the original owner.
When I power it on, it makes a constant horrible, loud noise, like a T-Rex taking a dump, only louder and worse.
It only just started doing this. I checked the cables, etc. They seem OK. And it worked OK all day, even after I did a Denon setup/calibration. And watched some TV and music.
Then the next time I powered it on, it makes this roaring noise and I have to shut it off immediately. Indeed, I did move the speaker because I was setting up a new amp, and maybe the jiggling broke something loose that was "old"?
I emailed a local "shop" with the symptoms, and he said: " your power supply is going out and the amp needs to be refurbished. "
Anyone know about this kind of failure?
Thanks
