INTRODUCING THE T-2000 25
TH
ANNIVERSARY STEREO
INTEGRATED AMPLIFIER
The T-2000 25
TH
ANNIVERSARY stereo integrated amplifier is
one of Allnic Audio’s two KT150 stereo integrated amplifier
models.
Like all Allnic Audio products, the T-2000 25
TH
ANNIVERSARY has Permalloy (iron and nickel alloy) for its
transformer cores. Allnic is grateful to Mr. G.W. Elmen of
Western Electric for inventing Permalloy for transformer
core use, and in so doing, providing an enormous service
to recorded music listeners everywhere.
The T-2000 25
TH
ANNIVERSARY has the following features:
•
100 watts of high power output. The T-2000 25
TH
ANNIVERSARY is a push-pull, triode/pentode switchable
integrated amplifier.
•
Remote controlled 41 steps silver contact attenuator
ver.2. The T-2000 25
TH
ANNIVERSARY employs this house
made quality attenuator, instead of standard,
outsourced carbon film potentiometers. The Allnic
attenuator provides complete channel balance and less
distortion.
•
Powerful Driving Circuitry. Allnic believes in the
importance of using high-quality, low noise and powerful
driving circuitry in all its amplifying devices. The T-2000
25
TH
ANNIVERSARY uses only two stages of driving circuit
to a38dB of voltage gain, instead of three or four
stages as one finds in many conventional integrated
amplifiers. This results in less coloration and more speed
in signal/sound reproduction. In the T-2000 25
TH
ANNIVERSARY, we employ the D3a tube in triode mode
as the second stage driver tube, with a load of about 5K
ohms, and using 20mA of current. The listener can easily
hear and even "feel" the differences between this design
and other, more conventional, ones. Please imagine, as
you listen to the T-2000 25
TH
ANNIVERSARY , its sound
compared to the sound of an integrated amplifier with
conventional 12AU7 or 12BH7's used as drivers, with a
load of about 47K ohm, and using 2 to 3mA of current.
•
“Full Engagement" Output Transformers. Conventional
output transformers use pre-set secondary windings to
accommodate 4, 8 and 16 ohm loudspeaker loads.
However, these conventional transformers utilize only
one secondary winding at a time, while the other
secondary windings remain "idle". This approach has
two adverse effects. First, the output transformers are
not working at their maximum efficiency, reducing their
output relative to their potential. Second, the "idle"
windings are not actually "idle"; they are subject to
parasitic oscillations, producing their own "signal". This
undesirable electrical information is additive to the
transformer's output, distorting the amplified signal
going to the loudspeaker. Allnic's "Full Engagement"
transformers address these issues by having 4
independent, secondary windings which are always fully
connected, never "idled". This means that all secondary
windings are always connected to your loudspeakers,
regardless of which output switch position you use (4
ohms or 8 ohms or 8 ohms or 16 ohms, depending on
the factory configuration you have selected). The result
is that there is neither a loss of transformer output
efficiency, nor the introduction into the output signal of
distortion from parasitic oscillations of the secondary
windings.
•
Large Nickel/FeSi Core Output Transformers. As with our
other models, Allnic uses very large output transformers
(96 mm) with nickel, mixed with FeSi, cores. This
provides for higher inductance with fewer windings than
