It doesn't feel loose. I'd say it's the circuit!
I'm pretty sure I'm getting no noise at all on any of the channels. Is it a single noise source which feeds all 4 channels? Again possibly a problem with the circuit in question?
I need to get the case off and check for loose connections. Problem of course is the holiday is over and I'm back at work. Where did all my spare time go?!
