AE1 Stereo Tube Amplifier Kit

Single-Ended EL34 HiFi Tube Amplifier     

Build your own point-to-point stereo tube amplifier.
A comprehensive DIY kit for high quality custom tube audio.


Everything you need in a clean and modern design

Great visual design is important for an end-product you are proud of. This is a showpiece in your home that your friends and family will see and ask about. A custom-designed chassis holds the components functionally but also beautifully in your listening environment. Inspired by mid-century modern designs, the kit includes a carefully crafted hardwood and aluminum chassis that perfectly fit the transformers, tubes and physical layout of the circuit.

High quality audio

This amplifier uses a single-ended circuit customized for the components included, and based on designs used for many years and proven to have great performance. Components are sourced from carefully selected suppliers to be high quality. While not intended as a high-powered amplifier, you will get good power and great quality sound at reasonable cost and physical size.


Detailed instruction manual to learn how a tube amplifier works

You will walk away with knowledge that empowers you in this hobby. This may be the only kit you build, or it may be one step on a journey of learning and building. The kit includes extensive step-by-step instructions, photos and illustrations as well as a detailed circuit explanation, to not only build the amplifier but to understand how and why it works.

Eight months now since finishing the AE1 Stereo Tube Amplifier Kit and the sound just keeps getting sweeter & sweeter, I would recommend trying some "Tube rolling" as I did when I bought a set of matched Groove Tubes GT-EL34M Mullard Power Tubes - Medium Duet & Groove Tubes GT-12AT7 Preamp Tube which just made this already incredible sounding amplifier even better. It's been many years since I could really enjoy the true analog sound that was meant to be heard in album recordings and never have enjoyed such near perfect reproduction until now with the AE1 Stereo Tube Amplifier.

For the inquiring music listener, this is a triple win.  

First, if you wish to put in the time, you will absolutely begin to understand exactly how an amplifier performs the magic that it does.  This is better than a circuit theory class!

Second, if you like the time and effort involved in carefully crafting something lovely, putting this amp together is a complete pleasure.  And the instructions are superb, with Perry having anticipated an astonishing number of questions that the beginner might have about nuances of assembly.

Third?  Why, the sound, of course.  I was stunned by how good this amp sounds.  Clean, smooth and surprisingly punchy.  I personally think this thing compares well to my 80 wpc Kenwood in  terms of sound quality.  And don't let the 6 wpc rating deter you.  With reasonably efficient speakers this amp is capable of delivering very good volume.  The music just seems to pop.

Five stars, and highly recommended (if this sounds like your kind of thing.)  I can honestly say I'm sorry the assembly journey is over, but listening to the amp, knowing where and how the signal is being amplified, and reveling in the quality of the tube sound has really changed my musical listening for the better.

The AE1 Stereo Tube Amplifier Kit has been one of my best DIY experiences since I first learned to solder. The assembly manual is very well laid out with plenty of tips, photos, tube amplifier theory so you'll lean how it all works and AnalogEthos was very helpful with any questions I had along the way. This wasn't just a whole new DIY challenge but also a vast learning experience and once the AE1 was completed it gave me a great deal of satisfaction knowing I had built this incredible sounding tube amplifier with my own hands. It will be something you'll not only enjoy building but will enjoy listening to for many years.

Very easy to follow the excellent build instructions.  A great discussion of how an amp works is provided in the kit manual. Does not require any advanced electronics knowledge.

Easy to understand (for the layman) guide but also provides more detailed information about tube amps in general.All in all, makes for as much (or little knowledge) as the end user wants to extract. Either way I was very pleased with the results.

All components are included. All you need are some basic tools, including a soldering iron, and some time to enjoy building it!
