Klark Teknik

• As the title indicates, this guitar amplifier features a 5-watt tube power amplifier and a Celestion brand speaker.
• It uses a ECC83/12AX7 preamplification tube and a 6V6GT power tube for the amplifier section, plus a Celestion Super 8 GBA-15 speaker.
• The amplifier handles frequencies between 80Hz and 10kHz, with hum and noise -75dB below the rated power and 0.5% total harmonic distortion.
• It includes a Low input and a High input, with the former attenuating the signal by approximately 50% and the latter being easier to overdrive.
• While tone is always debatable, the increased dynamic range and even-order harmonic distortion of tubes produces the better sound.
