Mains power noise

[tawraste]

Hi all,
Sorry if this is already being discussed, but here goes.
I've fallen into the irritating noise trap, and I would like to cure it without spending hundreds of pounds.
So, I have discovered that with no guitar or lead plugged into my amp if I plug in the transformer for my harley benton powerplant that there is an increase in noise through the amp.
The signal to noise ratio is enough that I can't ignore it....
Unfortunately for me, the only way I could get the amp or the pedalboard on a different circuit would be to run an extension cable to the upstairs of my house which is less than practical.

The amp is a marshall vs265, power is uk 240v.

Are there any simple but effective products that I can just plug in?

Thanks in advance for your help

Could be the HB supply itself.

And yes, I've gone down the noise rabbit hole a while ago. These days I'm using Cioks power (hellishly expensive, but no regrets) along with an Ibanez PT Gate, and everything's fine, with ZERO noise.

Huh, well well. I picked up the power supply and the noise changed.
Moved it two feet.
Noise gone. Ffs
Thanks mate!
