Bass amp grounding/hum issues

[Steve Conner]

Glad the screen grounding trick helped

The amp looks very nice by the way, but out of interest, what's the cooling air path? I see it gets sucked in through a vent in the side, then the fan blows it into the bottom of the chassis, but where does it go next?

Thanks. To be honest with you I didn't think much about the air path. I suppose air exits chassis through the small tubes' openings and then from the back. The amp is still without top and bottom cover and I don't know yet how warm it will be during normal operation.
