What is a Cuculo series?

Cuculo series derives from the cuckoo played by a clarinet of Beethoven's symphony No.6. Cuculo series is the peripheral device. I combine a Cuculo series with a Raicho series and have the quality which is just used and the design. A Cuculo series has the width of the 119mm. For a Cuculo series,there are no screws in a front, a surface and a side.

Ignoring impedance matching increases loss

Since the output impedance of a general preamplifier is about 1 kiloohm and the input impedance of a power amplifier is 47 kiloohms, the loss due to impedance mismatch is 2.1%. If you use Cuculo-tube between the preamp and the power amp, the loss will be 0.21%. Ignoring impedance matching rather increases loss.

Vacuum tube buffer circuit

Cuculo-tube uses a tube buffer circuit. The tube is a low μ triode 12AU7 and the European name is ECC82. It features dynamic and low noise. The powerful bass and overtones peculiar to vacuum tubes are beautiful.

Made in Japan

For example, the original print board designed in us is made in a cooperation factory of Ogaki-shi.
"Toyota LEXUS" and "super express Shinkansen train" produces the printed circuit boards in this factory.
