The price has been drastically reduced. 2024/10/15 sales price 178,000 yen A tube power amplifier that combines the strength of 300B with the vividness of the high range. It can be comfortably used by those listening to recent recordings without feeling old due to the sound. You can choose to use the volume circuit by turning the power direct switch on and off on the back, so you can connect it directly from a CD player, etc., or use a preamp, so it's easy to use. The appearance is good with little feeling of use (Kobayashi Hitoshi)

Full maintenance down to the details such as deteriorated capacitors, resistor replacement, and main volume overhaul! The vintage MC30 is still loved today, half a century later. The sharp high range and thick low to mid range sound are nothing short of wonderful. Since the left and right sides come out clearly without interference, you can feel a better sense of localization than a stereo machine. The excellent separation unique to mono amplifiers stands out, and everything from jazz to classical music can be played well. You can see the exterior, dullness, rust, abrasions, etc. and a feeling of use (Kobayashi Hitoshi)
