Pre-amplifier pri64crane


60-series began in 2010.64craine-series is the fifth generation. We pursued dynamic and natural sound quality. We reduced the thermal noise of the NFB resistance, and the SN ratio improved 6dB. And, changed a condenser, and 1-octave spread.

It is equipped with the vacuum tube buffer circuit with the triode. The buffer circuit minimizes the influence of the signal cable. The vacuum tube is triode 5703 made in American Raytheon Co. It is a military subminiature tube and is strong in vibration and is high reliability.

pri64crane is a pre-amp equipped with the latest tone control circuit. This tone control circuit is low distorted with the fourth generation and is low noise.
