bithloman, you may want to post your question in a separate and new thread as it is a very wide sweeping question.

This is the gallery for Class D amps for people to post pictures of their on-going and/or completed builds. The questions and comments about measurement, components, or price that follow are usually specific to recent builds posted to the respective builders.

This is my first audio project, a stereo combo amplifier built using a TPA3116D2 board.

It has a bluetooth module with USB & SD card input, FM tuner, and 1/8" & 1/4" L+R Phono inputs. The amp has an EQ with Bass/Mid/Treble & Volume, and there's a speaker protection/delay board to get rid of power-on thump. It's powered by a 24V supply, with a stepdown converter to run the bluetooth module. The box is an open-back slant design built around 6 ohm speakers salvaged from an old Sony shelf system.

I'm really enjoying the flexibility of this little thing - it's a stereo guitar practice amp, a boombox, a radio, a media player, and bluetooth party speaker all in one.

Hi amigos,

Some pictures of my Purifi dual Mono amplifier with a "made in Italy" Custom Buffer (OP Amps Muse 03 / Muse 02) and some pictures of my NC500MP Dual Mono as well so you can compare the size. (NC500MP on Top)
