Pure A class premain amplifier using the KT-88! It is the successor to the popular TRV-A88S. It is suitable as a vacuum tube introductory machine. JJ Electronic's KT88 is used. The appearance is dull, there is a feeling of use such as rubbing against the lettering around the vacuum tube. (Nobuyuki Takahashi)
