auxinput - the only piece of gear I have left after the great sell-off is a 100W HDPlex linear power supply, which I bought second-hand.
It has 4 taps: 5V, 12V, 19V (using for my old Nucleus), and a variable outlet.
It never got hot when I was using all the outputs at once, but it is rather old, so maybe I should be upgrading it?
