CS-300x picture No.1 (View more large picture.)

CS-300X is equipped with English finnest Tube EL-84 produced by "MULLARD",which is welknown for high sound quality against its small size.
A high input sensitivity of EL84 does not require a complicated circuit and accordingly, it can create a low distortion output signal.
EL84 is nowadays produced in several countries, however, we used for CS-300X a premium EL84 of MULLARD(UK) which increased much a sound quality of CS-300X in spite of a bit evaluation of a cost of CS-300X.
For Driver circuit, we used a Five-Star-Tube of GENERAL ELECTRIC 5751(premium version of 12AX7A) which has passed JAN(Joint Army & Navy) standard of U.S. Army and has a very stable and reliable quality.
