The new Amp Camp Amp V1.6 chassis is custom made for your Amp Camp Amp. 

Available in silver or back front panels, with with or without a front panel power switch cutout. The ACA parts kit does include a rear DPDT toggle switch which could be used as a rear power switch if you didn't want to use it for any other function (bridge mode switching, LED dimming, etc), or of course just DIY. The rear panel and covers are intentionally made of easy to work aluminum so that it's easy to mod, however you want to mod it!

    This design is based on the 2U Mini Dissipante, which has an internal space of 230mm wide and 200mm deep (heatsinks). You can find more information and specifications on the 2U Mini Dissipante product information page. 


      • Heatsinks: 2 x 2U UMS heatsinks with the new 2U UMS 8 hole pattern drilled and tapped with M3 threads
      • Covers: 3mm black anodized aluminum
      • Front panel: 10mm silver aluminum, with
        • 2 recessed LED cutouts, 3mm in front, 6mm blind recess in rear

        • Front power switch hole:
          • 20mm dia hole in front, 22mm blind recess in rear
          • Compatible with 19mm "vandal proof" switches with 22mm bezel should you want to "pimp your chassis"
      • Rear panel: 3mm black anodized aluminum, with the following cutouts:
        • 2 RCAs
        • 2 pairs of speaker binding posts

    This project was my first amp kit. It went really well. All parts were there and working. Online instructions were easy to follow with ample photos and explanation. Just need some tools aside from the kit. Everything came pretty quickly, even the case from Italy. The amp actually works, and sounds good!

    Great sound AND great looks.

    Wonderful and easy to build amp kit. Great build videos and easy to understand builds instructions. Parts quality is very high...and the sound? Well, the sound is amazing. It drove my Tekton Double Impact with ease. My only wish would be to have a higher 4 ohm output rating. Highly recommended.

    Great Nelson Amp

    Bought and built amp to prove Paul Klipsch theory that all he needs is a good 5 watt amp to drive his Klipschorns. This Nelson amp is fantastic, does the job be yond expectation. Is a great addition to my home built F5 amp and Harmon Kardon Citation II refurbished amp. All three sound great. Are using amp as we write this review. Nice kit build. Questioned the solid wire and suggested that the transistors be labeled better for identification. Another great Nelson Pass low power amp.

    Good kit for a first time DIYer

    This is the first DIY amp I've built (well, first 2 actually, since I bought 2 kits). This package, with all needed parts, a well built chassis, labeled PCB, and clear step-by-step instructions, is a good confidence builder. For example, while I have soldered before, I had never soldered anything to a through-hole board (that will be immediately obvious in my pic below). This was a good opportunity to learn a little and work on that skill.
    The amps fired right up, and look great. The chassis is especially nice, considering the price. Sound-wise, they are not bad at all, and capture a nice bit of the single-ended class A "magic". I am quite impressed by the flexibility (stereo vs mono, RC and XLR input) and have experimented with all 4 operation modes. Each sounds a bit different and none are perfect, but the sound far, FAR exceeds what it should at this price range and a hack like me doing assembly. To me, this was the perfect price point/time investment to sample solid state class A and learn a bit about how amps work at the same time.

    ACA chassis

    Very nicely finished chassis, with enough room inside to add some modifications to the stock ACA kit. Photo attached shows chassis with ClarityCap MR coupling caps and Audio Note electrolytics, bypassed with small-value ClarityCap MR.

    Cute and cool !

    easy to build and looks very cool!

    High Quality Amp

    This is my second purchase of the ACA and I’m using them in bridged mono configuration. I’m a big Nelson Pass fan and this amp doesn’t disappoint. It’s a low power class A design and the sound is wonderful, especially considering the price. Everything about the kit is high quality, from the design to the packaging. Excellent communication from the DIY Store also. Highly recommended.

    Stunningly simplistic build high-quality materials

    Each chassis takes roughly 5 minutes to assemble you could not ask for anything more simple did not even have to look at instructions. Finished my custom built full range hi efficiency speakers just for ACA. Can’t wait to build my first preamp. I’ve built the universal power supply available at DIYaudio that was easy. For now my preamps I have used that work excellent is my DarkVoice 336 SE, IFI Black Label and Pete Millett’s NuHybrid Kong Nutube all work excellent enhancing the Amp Camp Amp.
