Which Pass DIY amp for lowest heat + power useage?
I'm already looking forward to next summer and wondering if any of the First Watt / DIY amps are especially cool-running? I have a chiller for my place, but it's too noisy to run when I want to listen to music.

then F5 - decreased to some 40-45W dissipation per channel
possibly with Toshiba outputs ( ask Zhoufang) , because the will suffer less with Iq decrease

I would be inclined to build a BA2 but use lateral mosfets and bias it around 500mA.

most definitely something from "seven easy pieces"
there's also a pic of nelson holding a class d amp he designed. there might be a schematic for that floating out in the world. |
