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.
Other luxurious parts included are
- Tube Shield-Base: 24K gold plated.
