Contact Kenny 016-2203431

Tubes : Electro Harmonix 6L6GC x 2, 12AU7 x 2.

The TU-8200 is auto-biased and you can swap EL34, KT66, KT77, KT88, 6550 and KT90—there are no switches to change. Just turn off the amp, let it cool down, and unplug before you roll tubes. The input tubes are 12AU7, allowing for numerous affordable tube-rolling options. If you are willing to unscrew the case, you can adjust a couple of small jumpers and switch between ultralinear, pentode and triode modes. The TU-8200 headphone out uses three resistors to connect to the output transformers.

3 amplification modes (triode, pentode and ultra-linear) can be selected using PCB jumpers - Ultra linear (8W + 8W) / Triode (4W + 4W) / Pentode (8.2W + 8.2W)

High quality PCB with 70um copper traces (double regular thickness).
Audio Inputs : 2 x RCA and 1 x 3.5mm jack
Audio Outputs - Speaker impedance selector switch - 8-16Ω / 4-6.3Ω
Headphone jack at front.
