I tell you what I saw when I opened up a Yamaha multimedia speaker system.
The powered subwoofer main board had a TH copper star tying the power supply
and audio grounds together.  It looked like a 1/2-inch wide copper
"octopus".  Pretty clever way of tying 8 grounds together at a common point.
I wonder where they sourced the copper star from?

Oh, BTW, I opened the case to replace the fuse in the power supply.  Rock
on, dudes...
