Luxman MB3045 Power Amplifier Luxman MB3045 Monoblocks for sale. Pristine condition. 2 power tubes, 8045g, replaced. Serviced, anything out of spec replaced. 100v. Extremely close serial numbers. Happy to post. Very carefully packed.If you know these amps you know how good they are. Valve nirvana.SpecsThe Luxman MB3045 is a vintage (c. 1975–1978) monoblock tube power amplifier featuring 50W–60W output, renowned for its "Quadra-Filar" output transformer and 8045G power triodes. Designed in Japan, it features a push-pull Class AB design, designed for 4, 8, or 16-ohm loads, with a 10 Hz – 40 kHz
This is a fair ask, slightly firm: A$5,500 sits above the median A$4,720 and above the 75th percentile A$4,917 for recent comparable AUD listings, so it’s not a bargain, but it’s also not wildly out of line for a desirable piece. The premium is about A$580 over the upper quartile, which is enough to make buyers want a bit more than just “present and working.”
What makes it worth a look is the model’s reputation as a serious old-school valve amp with strong build quality, proper scale, and the kind of refined, authoritative sound people chase in this price tier. If it’s genuinely clean, fully functional, and ideally includes original boxes or paperwork, that helps justify the ask; if not, I’d want either a lower price or proof of recent service, because age-related maintenance is the main thing to budget for on a piece like this.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Luxman traces its origins to 1925 in Osaka, Japan, when brothers T. Hayakawa and K. Yoshikawa launched a radio equipment division within their Kinsuido picture frame import business, coinciding with Japan's inaugural radio broadcast. Initially importing components, the company soon pivoted to in-house manufacturing of transformers and switches, birthing the Luxman brand and establishing it as one of Japan's oldest electronic component makers. This heritage of precision engineering has endured through ownership shifts, including stints with Alpine and Samsung, before returning to Japanese hands in the early 2000s under dedicated Luxman Corporation.
The brand specializes in luxury high-end audio components, with a storied emphasis on amplifiers—both integrated and power models—preamplifiers, and receivers renowned for their warm, detailed sound. Luxman also produces turntables, CD players, tape decks, and speakers, alongside modern digital offerings like DACs, all handcrafted in Japan with custom parts and dual-mono designs for ultimate fidelity.
Positioned firmly in the high-end market, Luxman commands respect among discerning audiophiles for its timeless aesthetics, uncompromising build quality, and sonic refinement that bridges vintage warmth with cutting-edge performance. Classics like the 1970s CL-32 preamp and 1980s L-507 integrated amplifier fuel its collector appeal, while contemporary lines reaffirm its status as a boutique benchmark for those seeking "Ultimate Fidelity since 1925."
