I built up two board designs. One of the designs was for the regulated power supply, which I threw together myself from schematics I found online from Pedja Rogic. The other design was a parallel LM4780 amp done by Brian, who is known for building the LM3875 boards that were so popular before. I figured it would be best to etch/build my first double-sided layout that was designed by someone else.
The power supply building was quite simple, since it almost doesn’t need a PCB. I like using PCBs for anything I build, because “dead bug” wiring gets messy real fast, and is a risk for electric shock. I built both PS PCBs in a few hours, and they worked on the first try.
The double-sided PCB was an interesting one to build, as it involved a lot of complex soldering tasks to get done. Luckily my new iron is good at this sort of thing and doesn’t allow itself to get hot enough to be dangerous.
Now that everything exists in its own “permanent home” I can start to visualize how it will all fit into an enclosure. Pictures of the built boards will come soon, and I will post the PCB artwork for my power supply here as well.
