Our Thoughts RADAR AI

Is this the sort of tested spare you want to grab cheaply for a working amp or stash? At £15, this sits well below the £61 25th percentile and miles under the £129 median, so it reads as a strong bargain rather than a merely fair ask.

What makes it worthwhile is simple: ECC83/12AX7 valves remain a staple small-signal tube, and a tested example at this price is useful for swaps, troubleshooting, or keeping as a backup. The main thing to check is whether “measures 1.5mA” means both sections are reasonably balanced and whether the seller can confirm low noise, no microphonics, and acceptable test readings, since that’s what matters most on these.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Dual

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.
