Elekit TU-8200 Tube Amplifier Kit (SE 6L6)

Over the past several years I have been enjoying an Elekit TU-879S Stereo Tube Amplifier Kit paired up along side of Fostex FE206E high sensitivity speaker drivers in Dallas rear-loaded horn enclosures.  I put a number of hours on the Elekit TU-879S, enough to fully consume the stock EH 6L6 tubes and to cycle through a number of power tube sets before deciding on JJ EL34 blue glass tubes.  Throughout this time the Elekit TU-879S amplifier has been reliable and a good performer sonically so it was disappointing to hear that the popular TU-879S tube amp kit had been discontinued.

However, there is good news - the follow-up tube amplifier kit to the Elekit TU-879S, the Elekit TU-8200 is now available from TubeDepot (USA) and VK Music (Canada).  The renowned Elekit designer, Mr. Fujita, has gone back to the drawing board to design a superior tube amplifier kit from top to bottom. The Elekit TU-8200 will allow the kit builder to enjoy fine tube audio sound in just a few evenings.

Some of the improvements over the Elekit TU-879S tube amplifier kit include:
  • Three Selectable output modes - Ultra-linear, Triode, or Pentode by changing a jumper on PCB.
  • TU-8200 kit ships with a R-core power transformer that supports 100V, 115V, 200V, and 230V mains. 
  • Improvements to the audio and power supply circuitry.
  • Headphone output.
  • Optional Elekit PS-3249 DAC to decode audio from computer USB source.
The Elekit TU-8200 tube amplifier kit ships with Electro-Harmonix 6L6GC power tubes, but will also accept a wide range of other power tubes such as 6CA7, EL34, KT66, KT77, KT88, 6550 (and more) with no modifications and no need to re-bias.

The new Elekit TU-8200 tube amplifier kit looks quite tempting.  What I liked most about the TU-879S tube amplifier was the seemingly endless amount of tube combinations that were possible.  With the TU-8200 tube amp kit and the ability to select between Ultra-linear, Pentode or Triode output modes, the number of possible tube combinations are endless.  We are planning to take a closer look at one of the Elekit TU-8200 tube amp kits soon so please stay tuned for more updates.
