Designing audio power amplifiers
- eternityforest 4y agoGood to see that it covers class-D amps.
- ahartmetz 4y agoI am a BIG fan of class D amps and I recommend them to everyone. Small, low power, fantastic sound (everywhere, but especially the bass sounds incredibly precise) and dirt cheap.
- pjc50 4y agoIndeed. Only sensible way to do things in the 2020s, for both efficiency and power density.
- taffronaut 4y agoI would love to see a robust and repairable class D design make it to the market as a kit or module. It's the one disadvantage I see of class D. Most techs can fault-find on non-switching amplifiers, but blown commercial class D modules typically just end up in the bin.
- mistyvales 4y agoHypex (and Purifi) are fairly repairable, and also sound amazing
- AdamH12113 4y agoI picked up a copy of this book when I needed to design a class AB amplifier for non-audio purposes and found it very helpful. There’s a lot of theory and discussion of different options (transistor types, bias networks, etc.) rather than just presenting one “right” way to do things.
- exabrial 4y agoOn the opposite side of the spectrum: https://www.amazon.com/Designing-Tube-Preamps-Guitar-Bass/dp/0956154522 https://www.amazon.com/Designing-Tube-Preamps-Guitar-Bass/dp... I designed and created my own single-ended EL34 based guitar amp. This thing sounds bloody incredible when the output tube is in full tilt. It used a solid state power supply to decrease weight (from AliExpress), but ultimate bit the dust because the switching module was so unreliable.
