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.

      This is a nice amp right out of the box but with a few added parts it's a great amp.
      I originally installed the 8200DX Capacitor Upgrade kit, but I was not completely satisfied with the sound. So I replaced the four Amstrans AMCO 104 Metalized PET film capacitors from the DX Cap kit with four Sprague Orange Drop Polypropylene Capacitor 716 Series .100µF / 600V (Part number: CP-OD716-100-600V) and left the Sanyo OS-CON organic capacitors from the DX upgrade kit installed.
      I was pleasantly surprised with a clearer less muffled sound with the orange drop caps.
      I replaced the 9 pin tube sockets with ceramic sockets (Part number: SK-9PINPC) simply for better heat resistance over the stock sockets. I took it a step further and added a couple of 9 pin socket savers (Part number: SK-9SVR) to lift the 12AU7 Tubes up and the amp runs even cooler now.
      Being a kit you can easily do the mods right as you are building it, and the parts I used are available right here at TubeDepot
