The appeal of the KT150 vacuum tube is its dynamic and powerful sound. The circuit configuration of the output stage of class AB push-pull was selected to draw out its features to the fullest extent. The output is 100W + 100W (8Ω), and it drives various speakers powerfully and conveys the hot energy of music as it is.
In order to bring out the powerful sound of the KT150 vacuum tube, a powerful power supply suitable for the KT150 vacuum tube is required. The large-sized toroidal transformer is carried in the power transformer used as the key. In addition, a SiC Schottky barrier rectifier diode with fast response and low loss is used for the rectifier element. Combined with the toroidal transformer, it realizes an efficient, powerful, and quick-response power supply.
Bias adjustment is necessary to keep the tube working optimally when the tube is replaced or used for a long period of time. With MUSASHI, you can easily check the bias current with the bias meter laid out in the center of the front panel. There is a bias selector and a bias adjustment volume on the top of the chassis. While checking the bias current of the vacuum tube selected with the bias selector on the meter, you can easily adjust the bias adjustment volume to the optimum value.
MUSASHI is a pre-main amp, but it can also be used as a power amp with a simple switch. The rear panel has a MAIN IN input terminal and its ON/OFF switch. When the switch is turned on, the signal input to the MAIN IN jack bypasses the input selector and volume and is sent directly to the main amplifier circuit. You can enjoy it as a stereo power amplifier that allows you to fully enjoy the performance of the KT150 vacuum tube.
The first thing that catches your eye when you look at MUSASHI is the uniquely shaped 4 KT150 vacuum tubes, 3 large glossy black transformers, and the beautifully shining stainless steel chassis. Finished in a fearless design with a beautiful contrast between black and stainless steel. An 8mm-thick aluminum cutting top plate is attached to the top surface of the three transformers to reduce the vibration of the transformer and improve the heat radiation effect.
It comes with a remote control that can be operated from a distance. Input switching, volume up/down, and muting operation are possible.
