First of all the top hat speakers are NOT done yet. I have both of the top parts done and an waiting for my nephew to make the rest of the wood parts. He is in an after school club that builds robots to compete against each other and it takes up a lot of his free time so I have a feeling that the top hats will not be done for several more months. : (
As for the first amp, I gutted most of the old amp and only re used the transformer and the front mounted LED UV meters as well as the main power switch, power cord, and fuse holder. I put in the two chip amp boards, larger heat sink, power supply board, and rear connectors. The amplifier boards came from chipamp.com and they are a really easy board to solder up and use. They put out around 55 watts and sound really good. I'm pushing some pretty large speakers with the amp and it stays cool under full power. I think I'm going to install a larger transformer soon as the one that came in the case has a really low va rating, but for now it's working great.
Next up is a DX blame Supercharged amp build. I bought some boards a while back and recently ran into a case that will work out pretty well for the two boards. I still need to order all the parts as well as a transformer so it's going to be a slow build but I will post a few picts any way. I also have boards for a DX Blame Destroyer amp that puts out 250 Watts per channel @ 8 ohms but after pricing out parts I realize that they may never be finished as it will cost around $500 for all the parts needed! I will just hang on to the boards and every time I order parts for something else I will add a few extra parts for the amp.
What type of projects are your nephews asking you to do?
