Chauffeur OD squealing

[Grazza]

Just finished another build and I have plugged it in to see how it goes and it's not good!
Chauffeur passes sound when not on but high pitched squeal when on. I've never experienced this before. I love some input on how to trouble shoot this one.

1 and 7 are the outputs. You should get audio on any inputs that aren't vref. Some stages are inverting, but not all.
Hope it is sorted for you.

Ok, thanks. Should hopefully be good to go.

Yep, as soon as it was in the box, it started squealing again. If the edge of the pcb is touching the inside of the enclosure in any way can that cause this?
Spewing too, it worked fine out of the enclosure last night

I just keep looking at that footswitch. Can you post another pic from an angle that shows the clearance there so I can stop wondering?

I'm pretty sure it's not the switch, it was actually finally 100% working before it went in the enclosure. I don't like how it fits in the enclosure im thinking about drilling a new one and seeing how it goes. Don't like the jack locations or PCB fit

PCB is kinda jammed in against the screw posts of the enclosure, could this distort PCB or effect things?

Now it doesnt work outside the enclosure. I get a small amount of signal coming through and a whirring in the background like a plane engine is warming up. Assuming thats the charge pump. WTF.
