INTRODUCING THE M-3000 MK 3 MONOBLOCK POWER AMPLIFIER
The M-3000 MK 3 monoblock amplifier is Allnic Audio's top of the line, parallel push-pull power amplifier
model. Like all Allnic Audio products, the M-3000 MK 3 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 M-3000 MK 3 is an updated version of the original M-3000. It uses the new, powerful and musical KT170
power tube, with requisite changes to transformers and several minor circuit elements. The MK 3 has the
following features:
• 240 watts of high-power output in beam tetrode mode, 120 watts in triode. The M-3000 MK 3 is a parallel push-
pull, triode/tetrode switchable power amplifier.
• Powerful Driving Circuitry. Allnic believes in the importance of using high-quality, low noise and powerful driving
circuitry in all its amplifying devices. Therefore, in the M-3000 MK 3, we employ the powerful 6S4 triode tube as
the second stage driver tube. 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 M-3000 MK 3, its sound compared to the
sound of an amplifier with conventional 12AU7 or 12BH7 tubes used as drivers.
• "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 that 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 (114 mm) with nickel, mixed with FeSi, cores. This provides for higher inductance with fewer
windings than other designs can provide and results in the great benefit of an extremely wide range of output
frequencies.
•
"Soft-start" Circuitry. Allnic uses soft start circuitry that, after sufficient warm-up only, provides the high voltage
supply to the plate of each tube. This protective design results in prolonged tube life and fewer and less frequent
issues with tube performance.
