Here is the link to DIY Audio page on the Amp Camp Amp. This is a Nelson Pass amp of 8x2 with a 15watt monoblock option. It is single ended class 'A' which means NO push pull. And mainly 2nd harmonic distortion products. This amp is WELL reviewed and listeners love its good sound and ability to drive higher sensitivity speakers. I would judge this amp to be perfect for either a very high sensitivity stereo system OR a near-field system in Den or Office. If I had a kid going off to College? This would be a short-list item, but unfortunately Theft Bait. The KIT is complete at <320$ and will take the non-lunatic maybe 5 or 6 nights of a couple hours Per, than a couple hours to adjust per directions. Tools needed are minimal, but DO include a decent DVM and selection of hand tools as well as a soldering station. You'll also need good solder, a solder sucker, some solder Wicke and a good safe Work Area. The Hard Core type will take a weekend. diyaudiostore.com/products/amp-camp-amp-kit?variant=7072933085218 |

If someone has the skills, I guess I don't see how this could be anything but a win. $320 for a Nelson Pass design? Come on.

At the end of high school I took a job in a electronics place. An older Japanese lady named Hiro taught me how to solder. I got quite good that summer (1989) and worked at the same place the next.
The lament is that I haven't soldered since because there have been several projects especially this one that look amazing if you have a little skill.
Anyone here build one?

Built several Heathkits and Dynakits back in the day, both audio stuff and a couple of color TVs. But nothing recently. I'm seriously thinking about building DIY Atmos in-ceiling speakers for my Home Theater that I've put off for too long. I really did enjoy the assembly and soldering of the PCBs in the kits and think I'll enjoy doing the same for the crossovers in the DIY speakers.
Wouldn't want to make a career of it, though......
Cheers!
Chuck

I have a pair of amp camp amp monoblocks with external linear power supplies, I can verify that they do sound quite good, the power supplies take them to another level over the cheap pc ps.I would describe their sound as a slightly warm, more so than emotiva but not quite mcintosh.

A friend built a different Pass Labs amps. He had fun, but he made some big mistakes and had some issues (his fault, not the design's fault...not a good idea to heat the printed circuit really high at solder points!). It would be fun to build this one.

The 'new' version 1.6 has a 'better' PS of 24v / 5 amps which ups power output to 8x2 from 5x2. I think the original was 19v and less current. A good linear, which really is pretty easy to 'cookbook' MIGHT be better than the switcher, but I'll rely on Pass not getting too wound around the axle on that particular issue. And several parts lists for such linears on some of the posting sites devoted to the ACA. Reallly VERY popular and well regarded. Personally? I'd buy / build the kit as issued. Endless opportunities for mods / improvements down the road. |

Cheers! Chuck For funds when while going to uni I was a roadie for couple of bands, plus built lots of kits, pre amps, sound mixers, cross overs, power amps, speaker arrays etc plus strobe and other light controllers. Also repaired cables, microphones, guitar pickups etc. I still do a bit of soldering, although mostly crimp connections on the race cars' wiring harnesses. Cheers Gary |

Endless opportunities for mods / improvements down the road. Actually, the purpose of using a PC power supply brick as it pertains to the stock Amp Camp Amp is for safety reasons. The ACA was designed as a way for a beginner hobbyist to build a great sounding amp, at a lows cost. Pass noted that building power supply is an added element of danger that steer many beginners away from taking that first leap. |

Well at least this is not vacuum tube. Now that can get exciting.

After building two tube monoblocks these amps should be a piece of cake to build!

Yeah with a 600 volt rail or so. It makes quite an impression on you when mistreated. Causes injury or a trip to the beyond.

One hand in pocket goes a LONG way to keeping you safe with higher voltages.
Once vaporized a multimeter used to measure 20KV to 160KV (using high voltage probe) when the circuit under test
ARC'ED thru the meter. OOOPS!
Device under test had ALL its safeties defeated. Door interlocks? Ground strap? High voltage section was in its own room on huge (in feet) ceramic insulators and otherwise no direct electrical connection ot outer enclosure.
Be VERY careful when measuring an energized circuit.
