Primaluna 12Au7 Silver label tube pair - brand new and unused. Good to have as spares or replacements. Happy to ship at cost or you can pick up from 2232 Grays Point. Check out the other tubes I have for sale, if they are still available!
Timing matters here because 12AU7 valves are a mature, evergreen part rather than a fast-moving product, so condition and provenance matter more than model-year churn. At A$150, this sits above the A$127 median and just over the A$139 upper quartile from recent AUD comps, so it reads a touch ambitious rather than a bargain.
That said, if it’s a clean, tested matched pair or quad from a respected maker, there’s real value in buying into a well-regarded tube with broad compatibility and easy resale. The upside here is straightforward: these are the kind of valves people keep on hand for tuning tone and rolling into preamps or phono stages, so a well-kept set can be a useful, low-risk buy. If the listing includes test results, low hours, or original packaging, that helps justify the ask; if not, I’d still expect a little negotiation room.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
PrimaLuna, a boutique Dutch hi-fi brand, emerged in 2003 from the vision of Herman van den Dungen, a seasoned industry veteran with over 40 years of experience. Born in the Netherlands, van den Dungen had built his reputation earlier through Durob Audio, founded in 1975 as one of the first high-end importers in the Benelux region. Drawing on decades of tinkering with vintage radios and turntables, he launched PrimaLuna to democratize elite tube amplification, blending European design ingenuity with rigorous quality oversight in Chinese manufacturing.
The brand specializes exclusively in vacuum tube amplifiers, including integrated, power, and preamplifier models across series like ProLogue, DiaLogue, and EVO. PrimaLuna's hallmark is its unique construction—point-to-point wiring, custom transformers, and tube rectification—prioritizing sonic purity, longevity, and minimal servicing needs over broader categories like speakers, DACs, or turntables.
Positioned as high-end yet accessible, PrimaLuna occupies a niche among tube enthusiasts, earning acclaim for delivering "joyous cost-value surprises" through reliable, musically engaging performance that rivals pricier competitors. Its reputation for dependability and superb sound has solidified its status among discerning audiophiles worldwide, underscoring Dutch precision in a crowded market.
