Amp Camp Amp Chassis
Description
The Amp Camp Amp V1.8 chassis is custom made for your Amp Camp Amp. If you have a previous version of the ACA parts kit see our ACA upgrading information page.
This chassis ships from the US. If you are an EU resident EU customers can still buy the chassis intra-EU, click here for details.
V1.8 chassis has two new features:
- New V1.8 rear panel silkscreen diagram clearly showing how to select all 4 modes (1 stereo, 3 mono) and how to wire inputs and outputs
- Improved more secure cover mounting system using weld nuts and hex head screws
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.
Details:
- 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

Customer Reviews
I taught myself basic electronics and soldering for the express purpose of building this amp and I'm glad I did. The project was fun, taught me how the otherwise mysterious insides of these magical boxes work and resulted in such a great sound that I bought a second to set up a mono block system. These will be driving a pair of Klipsch Forte 1 speakers and I am amped to get them running (get it? amped? I kill me!).
I had a minor issue (right channel input on the PCB was backwards) which I posted on the forum and received an immediate response that helped me sort it out. If you are trying to decide if you should buy the kit, stop reading this and just add it to your cart.
To DIYAudio, do your customers a favor and have a technical writer put the online instructions together. There are too many paths between version iterations which can drive the reader to the wrong set of instructions. The documents that were included in the first amp kit were not included in the second and unfortunately I did not keep them for reference. That didn't stop the build but did create some extra work.
So happy with these amps ( got two). Using them as mono blocks with the schiit freya + tube preamp. Great sound. Sounds cleaner than my 80w/ch class AB and 150w/ch AV receiver. Using my Elac unifi UB5 bookshelf units with it :)
Enjoyed the build. Remember my father when he built his heathkit tuner and wharfedale full range enclosures in the 60’s. Thank you DIYaudio !
The chassis included all required hardware. The front panel is understated and elegant. The back panel has clear markings for each of the connections. For the top and bottom panels, there is a difference in finish for one side vs. the other. The only things I would change would be to include a 2mm hex wrench for the top and bottom fasteners and to break the sharp edges on the heatsinks. Those edges are only an issue while assembling; they are recessed once assembled. Overall, I am very happy with this purchase.
This was a first build for my niece (12) and nephew (14) and they are quite proud of what they built. Recommended!
This is the first DIY amp I’ve built with not needing tubes costing more than the base build!
A small confession – I just couldn't help but build it with some upgraded Mundorf and Sprague Atom caps and for good measure, Duelund cable.
Paired with an Elekit preamp and some Omega stand mounts the sound really does brings a smile to my face. As a bonus, it heats the room quite nicely.
No wild claims about it being better than my bigger (and far more expensive) EL34/KT88 and 300B amps but it more than holds my attention and has kept the office EL34/KT88 Elekit power amp gathering dust the last few weeks.
No way that I could ever own a piece of Nelson’s best in NZ and so I’m very happy to have spent and afternoon with soldering iron in hand.
Out of interest, I've ordered a linear power supply and a matching case. I t will intersting to see wht a change it brings. Guess I may need to put a blue LED into the pre........
I had a blast and learned SO much building these ACA amps. I had never built an amp before and had very limited soldering experience as well, so this was a perfect first project to tackle. The instructions/photos are top notch and super helpful. I would highly recommend to anyone, just take your time and you'll knock it out in no time. The best part however... these amps sound amazing!! The warmth of these class A amps is sooooo nice! Give them a try, you won't be disappointed.
Thoroughly enjoyed the build process, which as a novice, took me about 1 day for each amp. Chassis is well made, and the amps sound terrific! Been using daily, and I’m hooked on DIY! Great kits!!
Super easy to build, and just delicious juicy sound.
Love it!
I have some experience with soldering and building things but never an electronics product. The ampcamp amp sounded so good, I put in my main system and got a second for the dual mono lock operation. The online instructions were good but would have preferred one link with the 1.8 version from start to finish rather than switching from 1.6 to 1.8 versions. The materials are excellent quality and the final product is good looking!
