ELEKIT TU-8200R 6L6GC Single Vacuum Tube Amplifier Kit w/tracking New

Brand New.

Product Summary

This is a single-operation power amplifier kit that uses a 6L6GC output tube with powerful and natural sound quality. The output tube can be replaced with a similar tube, and is automatically set to the optimal bias for the output tube being inserted. In addition, you can easily switch the operation mode of the output tube, allowing you to fully enjoy the fun of a vacuum tube amp with this one unit.

■Equipped with our proprietary "active auto bias adjustment function"

In addition to the included output tube 6L6GC, KT66, KT88, 6550, EL34 (6CA7), etc. can be replaced.

Normally, in order to bring out the full potential of the installed vacuum tubes, it would be necessary to adjust the bias for each vacuum tube each time, but with the TU-8200, the bias is automatically adjusted to the optimal bias condition for the installed vacuum tubes. Equipped with a unique function "active auto bias adjustment function" that adjusts the bias. This allows you to easily and easily enjoy the sound that brings out the full potential of vacuum tubes.

■Easily switch between 3 types of connection methods

Powerful "pentode connection", "triode connection" characterized by delicate sound, and "ultra-linear (UL) connection" which has the best of both worlds.These three types of output tube operation modes can be operated using short plugs. It's easy to do just by replacing it.

■A conductive polymer hybrid aluminum electrolytic capacitor with low ESR is used as the cathode bypass capacitor in the voltage amplification stage.

This achieves high resolution and clear sound.

■Equipped with independent left and right FET ripple filters

The B power supply is equipped with independent left and right FET ripple filters cultivated in successive TU series. Combined with the DC lighting of the voltage tube, hum noise is kept to a minimum. In addition, it is equipped with an overcurrent protection circuit in case of trouble with the output tube.

■Equipped with headphone terminal

The output level can be switched to 3 levels by replacing the jumper on the board according to the sensitivity of the earphones or headphones.

■Uses a glass epoxy board with 70μm copper foil, which is thicker than normal and has low conduction loss and high heat dissipation effect.

■Most of the circuit section is mounted on the board. Wiring to the outside of the board is also done using a connector, making this kit easy to assemble even for soldering beginners.

[Precautions for use]

**About using KT120 with TU-8200R**

The KT120 can be used with upwardly compatible bulbs such as the KT88, but the heater current will be 25% higher than that of the KT88, and there will be no margin for power supply capacity, so avoid using it continuously for long periods of time to avoid trouble. please. (Especially during high temperatures in summer)
