We
introduced the special coil winding
structure used for T-1 (out of
production) which established a very
good reputation. Now we applied the
technology for mass-production type MC
Step-up transformer T-500 which we
introduce this time. The merits of T-500
are its high sound quality and
realization of low price.
Because a MC cartridge generates power
through a coil, it conducts a "balance
operation" at the both of beginning and
end of winding. We release T-500 for
high sound quality MC cartridge which
has the input portion of "full balance
correspondence" which optimize its
specialty to the maximum.
The
Model 411 II is mono-functional stereo
MC transformer to match with MC
cartridges with internal impedance (DCR)
of less than 15 ohm. The impedance
tolerance is 25 ohms. The transformer is
a toroidal design that applies the
toroidal winding to 0.05mm thickness of
supermalloy, layered ring-core. The core
volume has an external diameter of 25mm,
internal diameter of 16mm and height of
10mm. The termination of the wire is
directly connected to in/out terminal.
Therefore, the high efficiency of
toroidal transformer realizes extremely
low loss structure. It delivers the
signal from the cartridge without
coloration to the phono- terminal
directly. Model 411II is a modified
version of Model 411 and it has 32dB of
step-up ratio of approximately 40 times.
