Maintained by the manufacturer in 2023. A mulard type circuit is used for the circuit configuration, and an output transformer is mounted to achieve a wide range of frequency characteristics not typical of vacuum tube amplifiers. It is an amplifier with high performance and a careful, supple tone similar to that of Uesugi. There is paint peeling, but overall condition is good (Daiki Goto)
