The circuit is characterized by AC ignition, so you can hear some hum with the 38cm high-efficiency speaker, but in order to preserve the essence of the sound, AC ignition is used to reduce noise to the absolute minimum. (up to vacuum tube characteristics)
The OUTPUT transformer is an in-house amplifier. This amp was created with the aim of producing a sound close to the sound that was forgotten in the Showa era, but we aimed for a powerful one without iron distortion, making it an amp that won't run out of breath for saxophones or pets. Even if we do this, most people may find the sound fresh and new, but the sound we have arrived at through many mistakes to surpass the sound left by our predecessors is a natural sound.
It is the result of a lot of trial production and thought experiments with electric circuits, with emphasis on vocal expression, attention to sound, attention to parts, and focus on transformers. Good sound requires excellent sound separation, clarity, and good sound onset, but some listeners may say it's 50 to 100 steps, but after listening to it for a long time, this difference becomes a big difference, and it can be the difference between whether it resonates with the listener's heart or whether it is rejected.
These are the words of sound creator Yoshishiba. I'd love to!
