I am currently considering building an AMP from Class D's kits. I have built PC's many times, and wired home electrical panels, but have only rudimentary EE knowledge. However, I do think I have the gist of what's required. As a begin to put it all together, I'll likely get extremely frustrated if I forget things, so I wanted to make sure that I've covered all the major elements in advance. Here is what I believe a minimum BOM to be:
- AMP board.
- Toroidal transformer, rated to produce watts at XX% of amplifer's rated output.
- Power supply module.
- Power switch of choice.
- IEC connector for power.
- Mainline fuse rated at XX amps.
- CL60 thermistor inserted between signal equipment and ground.
- Front panel volume dial of choice.
- Rod to connect volume dial to potentiometer.
- Potentiometer for volume control (is this inserted on the low level line in?)
- Fans, if desired, and possibly a resistor inline to the fan to slow its speed, to make it quiet.
- Case of choice.
- Case feet of choice.
- Possibly grounded metal partitioning to elecromagnetically isolate the power supply from the amp board.
- Tools, elbow grease and luck.
