Hoffman AC30 grounding issue

[Oddvar]

Hi, I have just finished the Hoffman AC30 build.  I have great sound in it, only trouble is I have a terrible noise which sounds like a grounding issue. Anyone here that can suggest where it could be?  I have followed the Hoffman layout, and checked and doublecheck, but can't seem to find it.  Anyone?

The hum reacts to the cut pot.

Post close up photos, those who are more expert will benefit of it to give you help

I fixed it, sorry.

What did you find wrong?

Also, what's the status of that champ you were asking about a few days ago?
