TRON Electric Seven GT Phono Preamplifier I am original owner bought 2020 one of the last Seven's built. This is an all MM phono stage , the GT ultimate version with silver wiring and an enormous power stage. Exceptional parts and build quality as per the images. It presents as new as it should with only 50 hours on it and needs to be properly run in to sound its best!!! The beginning of lock downs and we moved to a house with an unstable floor so parked the TT and spun silver disks instead. Comes with original tubes, external Tron MC SUT (+20db) with MM pass through and dual switchable i
It’s a seller’s market for this niche, because this asking price sits well above the usual used range in your database: A$6,800 versus a median of A$510 and a 75th percentile of A$3,365. That makes it ambitious rather than merely strong, and I’d only call it justified if this is a truly exceptional example with collector-grade provenance or a notably upgraded spec.
That said, this is the kind of phono stage buyers chase when they want top-tier vinyl performance: the line is well regarded for extracting serious detail, low noise, and a big, authoritative presentation when paired with a revealing system. In like-new condition, the upside is real if you value rarity and want a statement piece, but at this level I’d want proof of originality, complete packaging, and a clear reason it commands such a premium over the broader used market.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Dual emerged from the Black Forest region of Germany in 1907, when brothers Christian and Joseph Steidinger began manufacturing clockwork and gramophone components in St. Georgen. The company adopted its now-iconic name in 1927 after pioneering dual-mode power supplies that allowed gramophones to operate from either mains electricity or mechanical wind-up mechanisms. This innovation marked the beginning of Dual's transition from component supplier to full-fledged audio manufacturer, establishing a foundation of engineering precision that would define the brand for decades.
Dual built its reputation primarily as a turntable specialist, becoming Europe's largest turntable manufacturer by the post-war era with over 3,000 employees across multiple factories. Beyond vinyl playback, the company expanded into cassette players, CD players, and broader consumer electronics throughout the 1970s and 1980s, demonstrating versatility across analog and digital formats. The company's focus on mechanical excellence and stable drive systems earned it recognition as a dependable, quality-focused manufacturer throughout its European heyday.
Today, Dual occupies a fragmented market position following corporate restructuring in the 1990s and subsequent ownership changes. The original German turntable line continues production in St. Georgen under Alfred Fehrenbacher GmbH, maintaining traditional manufacturing standards and appealing to vintage enthusiasts and collectors. Separately, Namsung Electronics markets Dual-branded consumer electronics in the Americas at accessible price points. The brand's legacy rests primarily on its classic turntables, which remain highly sought after by collectors and audiophiles valuing precision engineering and heritage craftsmanship.
