• 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 30th Anniversary uses only two stages

of driving circuit to achieve +40dB 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 30th Anniversary, we employ the D3a tube in triode mode as the second

stage driver tube, with a load of about 9K ohms, and using 12mA 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 30th 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 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.

• Analog Power Tube Current Monitors. In order to provide constant current (bias) monitoring for the

power tubes, Allnic uses a separate analogue current meter for each tube. The meters make it

exceptionally easy to see the status of each tube at any time and to respond immediately to any

variation in bias by use of the bias control knob for the relevant tube. The meters offer a simple,

unambiguous indication of each tube's status compared to conventional LED bias monitors.

• "On-the-Fly" Triode/Pentode Switching. Switching between triode and pentode operation can be done

"on-the-fly" at any time while the amplifier is in use.

• Beautiful 10KHz square wave response. See Figures 1-3.
