Usual amazing quality of DIYAudiostore products. All faultless and as specified. And of course great service from the Store answering queries. Thanks.
It was very simple to build. Mostly because of the very good and detailed instructions.
Love the board has test points too ... so its very easy too tune the pots and verify the build.
I like the sound too. A very fun build for me ;)
I very much enjoyed assembling the Amp camp kit. Instructions were perfect and easy to follow. My grandson helped me and it was a great way to spend time learning and enjoying the challenge. But the best part was reaping the benefits of completion and testing. Listened to Dave Rawlings Machine, Nashville Obsolete on vinyl and it sounded absolutely stunning and clear. I am very much looking forward to our next project. When available we will be ordering the Korg Nutube B1 Preamp kit. cannot wait!
I sent a FrontDesign drawing in with my order. CNC machining was required on both the front and the back of my 10mm panel, and Modushop did the work perfectly! Gianluca even contacted me by email to make sure they had it right. Great service and fast turnaround. The picture shows the preamp with its 2U custom panel. On top is a 3U Dissipante chassis which houses a Class A amp, also of my own design. Thanks, Modushop!
It all looks nice but, still waiting on chassis/box to come on stock where I can build it
Not had the time to.mount it yet.
Some friends got it and are very happy with it!
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.
I was impressed by the quality of the components and the chassis. Nicely done. Putting the kit together is quite straight forward following 6L6's construction guide. No problems. I wouldn't recommend this as an intro electronics, though,
Sound is very neutral with the standard setup. I haven't tried other settings yet.
One issue with the pre-amp is a loud thump when turning it on or off. But this is mentioned in Mr. Pass' original article.
Overall, I am very pleased and am looking forward to using this with a tube amp that I have under construction.
Well, yes, it certainly is. You can buy 20 lsk170 from somewhere or another for say $40. Match them yourself. That is what I did. Guess what? Out of the whole lot only two were well-matched. So, yeah, $29 for 0.1mA quad match is a very good deal, indeed.
The build was easy and the parts provided in the full kit were of excellent quality. The preamp performs very well. I wish I'd bought two!
great service, great on time delivery and fun to make
The price and quality are excellent.
Thanks for another solid performer for us to build. I've been enjoying it from the moment I set the final voltages. The chassis is the usual quality I've come to expect from DIYaudio's Italian supplier. The build went smoothly with great instructions. The design is simple and performs well beyond my expectations. I'm grateful for my son suggesting this project. I had the time to finish it in a few hours while he looks for some free time to start it sometime down the line. I'll probably forget the helpful hints by that time.
I bought Amp Camp PCBs, they are of very good quality. I have not yet completed the elements, so I will not describe the opinion on the sound of the amplifier yet. I rate the project handling as perfect. Jarek
This is a great preamp kit designed by Nelson Pass, comes with exceptional quality parts, and easy to build. The Korg Nutube 6P1 tube is not just a very cool device to look at, but also a very low power consumption vacuum tube which made it a perfect solution to convert it as a battery-powered preamp. Unlike a regular vacuum tube preamp, the Nutube 6P1 is not interchangeable. Although tube rolling is not possible to this preamp, Nelson adds a feature to adjust audio harmonics by a pair of trimmer pots each controlling the left and right separately. I can experience a different sound stage and 3D space by adjusting the value of the trimmer while the amp is powered on, how wonderful!
The kit already comes with audio grade electronic parts. Chassis is simple but elegant and solid, high-quality parts from Italy. I completed the kit with original parts which sounds very good already, later changed a few electrolytic caps with some polypropylene from the signal path suggested by the group member, this further improved the sound quality.
This little preamp kit is easy to build with lots of fun to discover. Worth every penny!
