*The color of the meter varies on the left and right depending on the burn. Maintenance has been completed, such as replacing 31 deteriorated parts, including capacitors, replacing meter illumination lamps, and dismantling and cleaning the front panel! It is an intermediate model developed in response to MC2600 technology. It makes me fully feel the thickness and luster of the mid and low frequencies typical of McKinn, even at low volume. The total balance is good, and the combination with modern speakers is also good. As for the exterior, there is a feeling of use such as dullness over time, and there are small scratches on the upper front and sides. Serial JFZ1552 (Yamato Yuki)
