Maintained in September 2022! This is a mono vacuum tube OTL amplifier that omits an output transformer, which greatly affects sound quality. 200W with a 16 ohm load and 150W with an 8 ohm load is enough power. It has excellent punching power in the mid to low range with a strength of driving power that you wouldn't think of as a vacuum tube. It is particularly compatible and recommended for ALTEC users. The exterior is dull over time, and scratches are scattered. Serial 3A 12/2106 (Yonejima Satoshi)
