Elekit TU-8200DX Stereo Tube Amplifier Kit

DIY-EK-TU-8200DX

This is the DX version of the TU-8200. It contains both the Elekit 8200, and the DX capacitor upgrade.

The descendant to to the wildly acclaimed TU-879S, the new Elekit TU-8200DX is now available. The renowned Elekit designer, Mr. Fujita, has gone back to the drawing board to design a superior tube amplifier kit. The TU-8200DX has many enhancements that allow the builder to enjoy exquisite tube audio in just a few nights.

The TU-8200DX ships with Electro Harmonix 6L6GC power tubes, but also supports a wide range of other power tubes such as KT66, KT88, EL34, 6550 (and others) with no modifications and no need to re-bias. Simply swap power tubes and the newly developed "active automatic bias adjustment function" will adjust the bias to the optimal level for each tube. No need to match tubes or manually re-bias ever again.
