| MARK LEVINSON No20L |
2,800,000yen(It is 1 set in two sets, 1986 release) |
Monophonic power amplifier which realized the
powerup pursuing the quality more than ML-2L.
The power-source part has
adopted perfect ± independent-source stream composition which carries a power
transformer in a positive and each negative, and each transformer has adopted
the mass toroidal transformer of 600A. Moreover, by the low-noise, it is
parallel to a filter capacitor and the quality polyethylene type excellent in
the impedance characteristic is adopted as it.
The high-speed regulator
is seen off in the power source of an output stage for loading and the clean and
stabilized power source from the driver stage with large capacity from ML-2L.
The complimentary push-pull circuit by whole page pure class A operation
is adopted as circuitry.
A balance receptacle is also possible at a
CAMAC termination and canon termination combined use.
High-power-izing
by bridge connection is possible.
