That is very cool, how did you go by handling the power supply, did you just plug both of them in to the the unit with individual plugs.
If I cant build it or fix it I really dont want it.

Great post, that was a real Amp Camp IMHO. Sure glad they worked!
And her sister is going to demand a system too! I can see it in her face...
It'll be a family tradition. Very good job getting everything ready so she could succeed!

Duder: The power supply is one from the DIYAudio store - its a laptop PS that provides 19V and 4A, so I just ran the power in jack to a switch and then split the power leads from there, one to each board.

Mark: Yeah, I suspect there may be more of these in our future! The girls also have a big brother - I think I'll need to get a few more boards... It was a bit of a challenge to decide how much of the work to do ahead of time. I wanted her to be able to help with everything, so it all needed to be ready to go, but I didn't want it to be too challenging so she'd lose interest. We spent about 2 hours populating the circuit boards. I had all of the woodworking done and the back panel pre-drilled. Things got a little slow when we started installing/soldering all of the signal in/out on the back. Perhaps I should have done just a bit more work ahead of time, but it worked out pretty well. It took us about 4 hours for the amp and about 1 hour for the speakers.

I was hoping that everything would work right away - trouble shooting would have reduced the thrill for sure! I had her stuff the board and cross parts off of the parts list as she installed them. I then double checked her work and we worked together to solder each part and then she did the trimming. She really got into it!

What an awesome post, and what an awesome dad you are! I am gathering parts for an ACA still and may try this with my daughter. Great idea. I really like the look of the maple chassis. Who says amps need to look like a metal box?! Like Bob said, if you are ever looking for an easy to build and great sounding speaker project to do with your kids, the Cornu is it.

....a beautiful amp indeed! I'm in the process of building an ACA and your post gave me the idea to mount the woodchassis itself to the heatsinks. I was originally thinking of metal brackets or braces for mounting but am now thankfully disabused of that notion. A gorgeous peice of 4/4 bloodwood will be used and should go well with silver heat sinks.

Hi Eric,

Very nice amp, I'm sure you guys had a great time building it.

I have also just finished building one, it's a sweet sounding amp, very musical. This was the first time my son was using some power tool like the drill and he also cut some metal. Very nice bonding moments. I have attached some picture showing how easy it is to built this amp.

p.s. I will most probably change the silver screws for black ones.
