Item Descriptions:

Easily enjoy the difference of sound by "vacuum tube" and "connection method" with this one unit

It is a power amplifier kit of single operation using output tube 6L 6 GC with powerful and natural sound quality.

The output pipe corresponds to the replacement to a similar pipe, and furthermore automatically set to the optimum bias for the output pipe being inserted.

Also, it is easy to switch the operation mode of the output tube, and this one allows you to fully enjoy the enjoyment of tube amp with this one.

· New function "active auto bias adjustment function" installed

Besides the attached output pipe 6L6GC, replacement of KT66, KT88, 6550, EL34 (6CA7) etc. is possible.

Normally, in order to fully draw out the capability of the attached vacuum tube, it was in each vacuum tube

Although bias adjustment is required every time, in the TU - 8200 it is necessary to apply

, A new function "automatic auto bias adjustment function" that automatically adjusts to the optimum bias state is installed.

This makes it easy to easily enjoy the sound that fully pulled out the capability of the tube.

- Easily switchable three types of connection method

Powerful "pentode connection", "triode connection" featuring delicate sound, "Ultra Linear (UL) connection" that combines both goodness,

The operation mode of these three types of output tubes can be easily done simply by replacing the short plug.

· FET ripple filter equipped independently

For B power supply, FET ripple filter cultivated in the successive TU series is equipped independently on the left and right.

Ham noise is kept to the minimum in combination with DC lighting of the voltage tube.

Also, in preparation for trouble of the output tube, there is a protection circuit for overcurrent.

· Power transformer for world wide

The primary side of the power transformer corresponds to the four power supply voltage bands of 100 V, 115 V, 200 V, 230 V.

It is also possible to use domestic 200V power supply as well as overseas use.

Adopted a glass epoxy board with copper foil of 70 μm thick, which is thicker than ordinary and has high heat dissipation effect with less conduction loss

· Headphone jack on the front

· Pilot lamp light color can be selected blue or green, whichever you like

- Most of the circuit part is mounted on the board.

Wiring with the outside of the board is also a connector type, it is a kit easy to assemble even for beginner soldering.

· Tools required for work

Driver (plus), nipper, radio pliers, scissors, tape, hex wrench, soldering iron
