I am aware that this topic has been discussed several times in the forum.
I am in the process to buy a new power supply for the dwarf to improve the noise which intermittently i am experiencing, mainly due to poor wiring/grounding in my house.
Looks like many users went for this from thomman
Can anyone suggest a similar good alternative from a UK supplier ?
If it’s Amazon, buy it and try it! I got one from Amazon that someone else on this forum had tried successfully but though it worked for them it didn’t work for me (HF noise). But like me, you can always return it if it doesn’t work.
