The diyAB "Honey Badger" Class AB Power Amp - 150W/Channel

  • 3900



Description

The first Class AB power amplifier to be featured at the diyAudio Store. It has been designed from the ground up with the sonic character, power output and most of all the DIYer in mind. With a basic power output of 150W at 8 ohms, this power amp is sure to have a place in every builder’s projects list. Not to mention its flexibility and adaptability to work with most output devices available locally in wherever country you may be.

Please visit the Honey Badger Helpdesk Thread for any questions you might have and for a definitive list of links to all articles and discussions about the amp itself, the build guide, schematics, and Bill of Materials.  The designer OSTripper is active over in the Honey Badger General Discussion Thread which is where all the action is.

Important note on resistor lead size: The resistor lead holes were intentionally made small by the designer. Please check the lead sizes of the parts in the BOM and use them as your maximum lead thickness before purchasing alternate resistors.

a realy very good amp !

I already build some Pass class A amp. but class A is not a good idea with powerful item.
I decide to try the Honey Badger. The design of Ostripper was very clever. There is all necessary element to obtain a fine result.
To my opinion there is in the schematics exactly what is needed to obtain a "good" amp but without complication. Except the fact that some holes are a little too small, the PCB is of good quality. I propose to clean the soldering side before beginning to obtain good solders. It is easy to populate.
The start procedure is well described and works perfectly... even if you made a mistake. When completed, I finally had the opportunity to hear nice music flowing from my speaker due to the exceptional quality of the Badger amp.
I am not disappointed and I begin a second one.
I can say it is a very good thing and a very musical amplifier.
Bravo to Pete Ostripper and thank you to Diy Audio Store to allow us to obtain such a result.

Excellent Amp

Built 2 pairs for a bi-amped ESL setup. They sound amazing and were easy to build. Amps are quiet and the detail is fantastic. I would highly recommend this amp build to others.

Quality boards, nice sound

I'm not done tuning it yet, but it is built and has been tested on big speakers, and it pushes them very well and sounds better than what I currently use in the living room. This was my first amp that I have built, and the support thread was very supportive. Very pleased with the overall experience and the sound is great! Nice amp, thanks!

I have had issues with this build from the beginning

This is my second set of boards the first I kept having issues could not get the dc offset working after several tear downs I bought a new set of board and got it working using all new parts and the same power transistors. I had the old ones working several times but they just kept burning out. Two things I found the parts list is confusing to many variations and suggestions I built the new ones piece by piece with the 2013 version on the Store. Second the through holes on the board are to small in many cases and I think drilling them out caused issues on the first set of boards in cases the power resistors would not fit. Third the foum as valuable as the people are and the help they provide is excellent however the thread on the badger needs a cleanup it’s to long and it has too many variations in the the tread we need one with just the current build it some of us me included don’t have the technical background to really understand all those. I envy the folks that do, for me it’s a hobby I love and have built many of these dyi store items without issue, but in part that’s paint by the numbers!

Excellent board quality

Excellent board quality (especially for the given price) including huge solder pads. Fast (< one week) and smooth delivery to CH. Looking forward to the build. The only points I could wish for at the moment are (i) a left/right symmetric design, (ii) place for pcb mount RCA terminals at the input, (iii) more closely placed speaker output and speaker ground terminals. But then again, it is a very solid design and build for a hardly visible price.

Nice and well made

I cant use my Dale RN60 resistors the holes are too narrow. Otherwise som nice boards

Quiet yet powerful amp!

If you follow the build guide you will have yourself a very nice amplifier, it's powerful with
loads of detail. I would suggest trying to run this amp at or near the 100ma max setting, it really opens
up at that point. The quality of the boards are really good and service from the store is always good.
