Amp Camp Amp Chassis
- Please note: This is a pre-order. Please read more on the The Amp Camp Amp Pre-Order Status Page.
- If you have built a previous version of the ACA, you can use this new chassis. Please see our ACA upgrading information page.
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
- "Pass ACA Class A Amplifier" silkscreen
- 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
- 1 11mm dia DC input
- 1 6.4mm dia power toggle / option switch
- 1 Neutrik D-Series XLR pattern
- Shipping not included, but is very economical
- V1.5 / March 2018
- First revision of chassis
- Added front power switch
- Rear DC jack hole enlarged from 8mm to 11mm
- Rear toggle switch hole enlarged from 6mm to 6.4mm
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.
wasn't sure what this would look like when ordering, but am very pleased with the quality of the amp chassis, not to mention heavier than I expected. the quality & looks fit right in in my big system
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.
Reviewing the whole package here. I prepped by watching some videos on soldering and getting some practice parts, and the assembly of the kit went smoothly. As a first timer, it took me longer than the estimate, but I was being super careful. Chassis looks nice, though the LEDs are too bright. Now powering vintage Jansens Z960s in a big room with an Airplay/Mac source, and the sound is great. Clear and crisp, no flab in the middle. It'll go plenty loud, well above what my family wants to hear. Some distortion at the max volume on the computer, but it doesn't need to be pushed that high to be plenty loud. It is quite warm, as folks have said. Overall, it was a lot of fun to build and sounds great - I'm super pleased.
