A hum is coming from my CA-1000 which I'm sure didn't exist previously. The same hum also comes out of the speakers, which definitely wasn't there. It's a new unit for me and it had problems when I first got it, so I didn't have much time with it before this problem, but again I'm sure it wasn't there.
It sounds like the power transformer - when I lived in the UK I had a power converter to use 120V electrics, and this sounds a lot like that. It's fairly quiet from the unit, a little louder from the speakers, and is not affected by volume.
The only thing I did to the unit before noticing the hum was replace the output transistors (with Onsemi). I guess it could be a cooincidence, but I'm hoping someone has some insight.
Thanks!
