Tube Amp Kits

Secret Chord Analogue can help you upgrade to a high-quality tube amplifier without you having to sell your soul at the crossroads.

You can experience incredible sound, and incredible value for money, by building your own tube amplifier from one of the meticulously designed DIY kits we sell.

Building your own tube amp from a kit is easier than you might think. You don’t need any experience with electronics and if you haven't soldered before we will supply you with online soldering instruction.

And if DIY is not your thing, you can utilise our build service!

There are two kit manufacturers we highly recommend: Elekit, Japan’s finest and Australia’s own Red Roo Kits.

Both manufacturers use A-grade components and their kits come with everything you need, including crystal clear instructions. And if it gets too hard or you feel you've made a mistake we offer a post DIY finishing service. 

As well as incredible sound and value for money, these kits come with a special bonus: the satisfaction of having built it yourself! You’ll be glowing like one of the tubes on your amp for years to come!

If you are going to build, consider adding eutectic solder: https://secretchordanalogue.au/products/eutectic-solder-20gms for a superior build result.

Testimonials

100% satisfied with the sound

I received both kits on time, and built the amplifier straight away.
The instructions were easy to follow, and not too verbose (10 out of 10). I am a Technical Author, and I could not fault them.
The quality of the kit components and PCBs was excellent. Beautiful design, and forethought. It is the best kit that I have seen. 100% satisfied with the sound - so full.

I lose three hours getting lost in the sound

Hooked theTU-8500 up to my NAD 326bee, by passing its preamp, and now whenever I put music on I lose three hours getting lost in the sound.
It’s clear, punchy and has a great soundstage. Very enjoyable to listen to.
With the phono you can really hear how every record is mixed & mastered differently.

The soothing output of the tubes

The TU-8200 is running beautifully; use it all the time into my Krix KDX Main speakers and it sounds wonderful. I am a reel to reel and Nakamichi cassette deck man. I run a Tascam OB44 and an Otari MX5050 MkIII, along with Nakamichi ZX-9, two Nakamichi 680ZX & #8217s , a Nakamichi 670ZX with High-Com plus two Pioneer CT-91A’s. These analogue sources sound fantastic through the TU-8200; 8 watts in ultra linear mode is more than enough for my listening room. As an ex broadcast engineer I just like the whole tape / recording / playback experience using CD and digital files as the sources. The analogue tape sound (when well recorded) and the soothing output of the tubes makes digital sources sound much better to me.

I am so glad I bought the kit

I have the TU-8200R operational. Powered it up this morning after assembling it over the last several days.
My first impressions - in the 20 years of being an audiophile, I have not listened to music of such warmth, separation, soundstage, the list goes on and on.
