The diyAB "Honey Badger" Class AB Power Amp - 150W/Channel
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.
|Dimensions||253mm x 76mm|
|Mounting holes||UMS Heatsink Compatible|
|Number of boards included||2|
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.
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.
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!
well designed and manufactured. Invites completion!
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.
I cant use my Dale RN60 resistors the holes are too narrow. Otherwise som nice boards
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.
If you follow the build guild to the letter you will have yourself a really nice sounding amplifier with a lot of power.
The boards are well made.
