Rotel RB970BXII power-amp hiss

[Damian]

Good morning!

Can anyone confirm if a faint hiss through the speakers, with nothing connected, is usual for the Rotel?

Many thanks!

Hi Damian
Just dug mine out of the cupboard
I get no such hiss, silent

Thanks for digging out and checking, appreciate it Steve!

I better go and check the bias and isolate a noisy transistor or something!

Right, just to answer my initial question. It's my mains supply, there's something on it that's causing the interference, my broadband is being affected by REIN so now I'm searching for the errant device.
