Arrived in the UK well packaged along with the B1, easy to assemble. Amazing Sound for the cost, thanks Nelson & the DIY team
& community. Made the Ash box with speaker terminals on the rear will house a filter inside.

ACA MINI-BIG Amplifier

Great kit, quality parts, easy to assemble. Most importantly the sound is amazing for the price. Thanks to Papa Nelson for the design. Thanks to the Diy community for the help and support.

Great kit!

This is an awesome kit. I tested its 5 watts per channel on Fostex ESR-206 with 98 db/1W meter and it is beautiful. The pairing with the acp-amp-camp-pre-amp (also available here, thank you!) makes it excellent. A beautiful, totally awesome combo.

One caveat: adjusting bias may be a bit of a challenge for the neophyte, but it is totally doable.

A Neat Kit That Even a Dolt Like Me Can Complete (And Enjoy!!!)

I took it slowly and surely despite several significant missteps. For those with a similar absence of electronic knowledge, experience, and confidence, this is a really nice little amp. Even the biasing, which in my opinion is the hardest part, went from impossible to comprehend and complete to completed confidently. I do suggest the use of an auto ranging DMM to avoid the uncertainty of selecting the proper range for the many, many adjustments to dial in the biasing successfully. I think its sound quality is actually superior to my ACA Amp Camp amp. Highly recommended.

Perfect Parts

As with parts sets I've previously bought for it's big brother the ACA everything required for the ACA mini was there in the kit and nothing missing. I wish there was a package with a tiny metal case instead of the heat sinks but it's good for the money and I value the convenience of a one stop shop.

Excellent kit. wonderful as tweeter amp

The lit is very easy to build. I am using the modules as balanced monoblocks to drive my plasma tweeters in a 3 way system with active crossovers. The amps have a high frequency extension to well beyond 50kHz and work very well.

Nice product

2 well packaged kits arrived in perfect condition. I have opened and looked at one of the kits, and everything seems to be there. Very well organized and packed tightly. I will build these kits when I can, and give a more elaborate report at that time.

Great Kit For Great Little Amp

This kit perfectly complements the Essentials Kit! Everything on the photo was in and made the assembly easy. So tt took me just slightly more than 1 hour to finish the amp. Great work, great packing - really happy with that. Thanks Nelson! Thanks ADIY team! Btw, for a long time I had been looking for a class A sand amp offering about 5 watts. Now it is done and I will see if I can send the few 25W cousins onto the shelf. Best Regards, Ernst
