specification of QA-111

Model no: QA-111

line stage pre-amplifier

Using the most common 12AX7/12AU7 / 6DJ8 / 6922 as the amplification section gives you the best small tube sound. With such a low price, it is still all hand-wired to the highest possible quality. For a richer and warmer sound please choose the 6DJ8/6922 type of tube. For better dynamics please choose the 12AX7/12AU7 type of tube.

The upper left photo shows a special version with enhanced Tx, solid-oak chassis and solid brass volume knob
