Collection: Tube Amp Kits

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.

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 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 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.
