    I'm making a pair of the amps as numerous comments on the web recommend bridged operation for any meaningful output. The original project was a one day "amp camp" for people to build their own modest amp. That led to the power brick to avoid house current for really rank beginners who never held a soldering iron before.

    I have shown a complete lack of critical listening skills, so I'll say something about the sound. Don't expect John Atkinson.

    Nice enclosure. Are you just adding two D/C jacks for those power bricks? I'll be very interested on your listening impressions.

    So I have to drill and tap the heat sinks for the PCB and solid state devices, since I didn't buy the pricey diyaudio chassis. The heat sink material is surprisingly tough. I was expecting dead soft aluminum. A solid state device hangs off both ends of the PCB, so 8 more holes. The heat sink is just wide enough for the PCB. There is another larger chassis available, but it has a hole in the back panel for an IEC AC jack, these are brick powered.

    I've been super curious about these. Looking forward to seeing the build and getting your impression of the amps.

    Assembled one chassis. Very good fit, some of the tapped holes need cleaned out. Everything screws to the heat sink sides. This chassis is available from many sources. Most have stick on feet. This seller includes bolt on feet, no holes or hardware for that. I may just epoxy them.

    The DIYaudio sourced chassis mounts a large round on/off switch on the front panel. I will probably move that to the rear, I do not have a good way to make a large clean hole in the 5/16" thick front panel. I will drill two small holes for two LEDs

    Try Classdaudiodotcom for high power low distortion amp kits. Or check with forum member SilverD, he has built several amps using modern components.These are maybe 8 watts of class A power with, as Wolf says, pleasing distortion. Audio Science Review kicked them to the curb, others love them. Build two so you have enough power. I will report when done. Reams of info on the internet.

    "They are low power high distortion units."

    Is that a typo or am I missing something here? I am more interested in high power low distortion units! I know, I am so gosh darn picky...

    Unless you have a pair and bridge them, yes, they are higher HD units- but pleasing 2nd order.

    It's a pretty spacious chassis compared to your projects.

    I'm also interested in the build and look forward to your opinion.

    You can find an illustrated build guide easily, diyaudio. They are low power high distortion units. I will post up pictures. They sell a custom chassis and $50 dollar power brick, rather expensive. I'm cheaping out.
Working...
