THESE AMPLIFIERS ARE BUILT AFTER THE ORDER
THE DELIVERY TIME IS ABOUT 18-24 WEEKS
300mW output power can be called sufficient output power for headphone amplifier. Moreover, it is also possible to listen to music with smaller volume by this output power also in a speaker system. Although it is impossible to take out big volume which is usually heard from a speaker, of course, when telephoning as BGM, it can be said to be sufficient value to use it on a convenient level. Moreover, originally, since this vacuum tube was developed as an object for small signals, noise characteristics are also excellent, and the resolution at the time of very small volume is excellent. Therefore, the place where sound is clearly reproduced also where volume is lowered as an object for BGM can call it an advantage. Moreover, although the amplification circuit of a two or three stages is used in many cases, in the case of this machine, the big amplification factor of a pentode is used, and it usually constitutes it from vacuum tube amplifier in only one stage of amplification circuit. It has succeeded in pulling out the freshness of the simplicity, therefore sound to the maximum extent.
The output transformer highly efficient despite small size is adopted as the output transformer of this machine using the same technology as the transformer adopted as the high-end model kind of our company. It was adopted as A-08S etc., the high Teflon insulating paper of evaluation was adopted as this output transformer, and the highest sound quality was aimed at.
