Features of This Unit
Outline
This unit is a non-feedback CR type phono equalizer ampli-
fier that is configured with the vacuum-tube-equipped SRPP
(Shunt Regulated Push-Pull) circuit.
Non-feedback CR type equalizer circuit
Various high sound quality parts that have been carefully se-
lected are used in this non-feedback CR type equalizer circuit.
Input stage SRPP circuit
The SRPP (Shunt Regulated Push-Pull) circuit that features a
low impedance output, prolonged life of vacuum tubes, and
many other advantages, is used in the phono equalizer sec-
tion.
Specially selected MC transformer
Four pieces of step-up transformers in which a super permal-
loy core is independently used are mounted. Independence
among MC-HIGH, MC-LOW, left and right respectively has
achieved richly expressive sound that can be produced only
by boosting with a transformer.
Articulation function
Magnetization of the cartridge or MC transformer that may
cause the deterioration of sound quality can be eliminated
with the use of reproduced sound signals. This function can
exploit the full potential of cartridges and achieve the sound
quality with a sense of openness.
Vriable cartridge load impedance
The load resistance variable function from 30 kΩ through
100 kΩ supports a wide variety of cartridges.
Setting of cartridge load capacity
The load capacity setting function with 6 positions supports
a wide variety of cartridges. Change in high-pass characteris-
tics allows sound to be adjusted to your favorite tone quality.
Switchover of gains
The gain selection switch with 3 positions (36 dB/38 dB/
40 dB) is equipped.
Output transformer
The output transformer with a super permalloy core is
equipped to achieve richly and deeply expressive sound. The
balanced output is also supported.
Analog meter
Analog meters with a sensitivity selection switch are intro-
duced to make various cartridge outputs available. The me-
ter-off function is also equipped. (When OFF is selected, the
meter needles do not move.)
