Allnic Audio T-1800 Mk2 Integrated Amplifier - Consignment
Condition: Used. Excellent, small chips on remote only (See photos)
Includes: Remote, Manual, Original box
SN: 25358
Made In Korea
Overview
The Allnic Audio T-1800 MK2 is a stereo integrated valve amplifier delivering 40 watts per channel through a push-pull EL34 output stage.
Its design incorporates Allnic’s use of Permalloy, an iron-nickel alloy, in transformer cores, alongside large 96mm nickel/FeSi-core output transformers. The transformer design uses Allnic’s “Full Engagement” configuration, in which all four independent secondary windings remain connected rather than leaving unused windings idle.
The amplification circuit uses two stages of driver circuitry, comprising two E180CC valves and one 12AY7 valve, with the EL34s forming the output stage, and supports 4- and 8-ohm loudspeaker loads.
A custom 41-step, remote-controlled attenuator with silver contacts provides volume adjustment, replacing a conventional carbon-film potentiometer.
The amplifier also incorporates self-biasing circuitry and individual analogue current monitoring for the output valves, allowing their operating status to be checked directly from the front panel. A soft-start circuit delays the application of high voltage until the valves have warmed up.
RCA preamplifier outputs allow connection to an external powered subwoofer.

Compared with the obvious alternative—a newer solid-state integrated at A$8,800—this is a fair price for a well-regarded Allnic T-1800 Mk2, landing exactly on the median of 11 comparable listings. It is neither a bargain nor an ambitious ask, but the model is specific enough that a good example can justify the figure.
The appeal is its push-pull EL34 design, delivering a useful 40 watts per channel with the musicality, drive, and tube-rolling flexibility enthusiasts expect from the format. Allnic’s 41-step silver-contact attenuator, autobias operation, and multiple RCA plus balanced inputs add real usability, while the amplifier has a reputation for controlled bass and extended treble rather than stereotypical softness. Confirm tube condition, remote, and service history; with those in order, A$8,800 is a sound buying opportunity rather than a premium.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Allnic Audio is a South Korean manufacturer founded in 1997 by Kang Su Park, who continues to design every product and many components himself. The company emerged from Park's earlier venture, Silvaweld, which he co-founded after returning to South Korea in 1990. Park's vision centered on creating high-performance audio electronics using proprietary all-nickel core transformers—the namesake of the Allnic brand—which he viewed as superior to conventional transformer materials for audio applications.
The brand specializes in tube-based electronics, particularly integrated amplifiers, power amplifiers, preamplifiers, and phono stages, with the latter category becoming increasingly central to the product line. Allnic is also known for designing and hand-building moving-coil cartridges. The company's initial focus on 300B-based amplifiers has expanded to include designs using alternative output tubes such as KT120. Allnic manufactures its own transformers using permalloy cores and maintains tight control over component quality throughout its product range.
Allnic occupies the high-end boutique segment of the audio market, commanding premium pricing comparable to established Japanese and European tube manufacturers. The brand gained early international recognition in Germany around 2000 and has since developed a dedicated following among discerning analog enthusiasts and tube amplifier aficionados. While not as widely recognized as legacy brands, Allnic has earned respect within the audiophile community for its uncompromising design philosophy, hand-crafted construction, and Park's personal involvement in every aspect of product development.
