Available for sale is a top spec McChanson SET KT150 UL/Triode switchable Tube Amplifier – with adjustable fixed bias, with Silk output transformers & uses an IT (interstage transformers– i.e. no coupling capacitors). This is a beast of an Amp, drives my 88db Speakers easily with dial barely ...
A$2,800 is ambitious against your own used-market anchor: it sits well above the A$2,194 75th percentile and far over the A$1,605 median, so this is priced at a clear premium rather than a bargain. For a buyer, that only makes sense if this example is unusually clean, fully checked, and comes with real extras or provenance that justify the stretch.
What still makes it interesting is the core appeal of a KT150 push-pull valve integrated: big, effortless scale, strong dynamics, and that dense, dimensional presentation tube fans chase. The excellent-condition note helps, and if it’s recent, stable, and complete with remote/manuals/original packaging, that supports the ask. I’d still want to confirm service history, tube hours, and whether any costly wear items are due, because at this price you’re paying for confidence as much as sound.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
McChanson Audio traces its roots to Sydney, Australia, where valve amplifier enthusiast Eric Chan has operated as a one-man workshop since at least the 1960s. Chan, a self-taught electronics tinkerer who built his first diode radio as a teenager, began crafting custom tube amps from his Burwood home, evolving into a true cottage industry. With decades of hands-on experience, he embodies the DIY spirit of hi-fi's golden era, producing gear that prioritizes pure tone over mass production.
The brand specializes in boutique vacuum tube amplifiers, including single-ended triode (SET) designs like the 8-watt-per-channel MarzE and push-pull models such as the Black Knight, often priced accessibly between $600 and $750 AUD depending on components. Chan also builds headphone amps, stereo power amps, and guitar amplifiers, with occasional forays into preamps using tubes like KT88 and 6C4N-EB. These hand-wired creations emphasize Class A operation and tonal warmth, appealing to vinyl lovers and tube purists.
McChanson occupies a niche as an underground cult favorite among audiophiles, particularly guitarists in Australia, the UK, and US, who praise its exquisite sound and build quality in online forums. Far from high-end luxury or mainstream mid-tier, it thrives as a vintage-inspired boutique operation—obscure yet revered for delivering exceptional value in a sea of factory amps. For the discerning buyer seeking authentic valve magic, Eric Chan's offerings remain a hidden gem.
