Hello from Rhodes- Greece

Hi to you all ,and thanks DIY Audio and Mr Pass for this fantastic amp .I got the ACA 1.6 one.
Everything worked fine even though I am a newbe in the DIY field.
But there is a kind of noise in one of the channels sometimes almost inaudable then it goes up and down in volume and sounds like a storm from afar.Please help. .Any ideas?

Welcome to diyAudio John :)

We have a couple of ACA threads in the Pass Labs section of the forum and so I would suggest you might be best asking there. It's a long thread but there is a lot of expertise over there.

First things to check would be whether the noise responds to physical input which would suggest a poorly soldered connection somewhere. Also try swapping the input around to make sure its nothing external.
