Offered is „Princess 274B Rectifier Tube“ by Sophia Electric as second-hand device from the category „Tube-Poweramp“ on audio-markt.de - the online market place for high-end. The advert with the number 737825578 ends on 09.11.2026 at 18:28 o'clock.
At €150, this sits well below the typical used asking-price picture for this tube, with the market median at €866 and even the 25th percentile at €180, so it reads as a genuine bargain rather than merely “reasonable.” Compared with what a new premium rectifier can cost, this is the kind of price that makes sense for a quick buy if the tube is healthy.
That’s the appeal here: these are sought after for their sound quality, and a good rectifier can bring a system a touch more ease, dimensionality, and refinement without huge system upheaval. For a tube item, “good” condition at this price is the right sweet spot—just confirm it tests well, the pins are clean, and there’s no sign of cracks or intermittent behavior.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Sophia Electric traces its origins to two small custom amplifier makers on the U.S. East Coast, evolving into a dedicated hi-fi brand in 2001 when Richard Wugang, a former banker, audiophile, and collector of vintage classic amplifiers, infused capital, marketing savvy, and industrial expertise. Based in Washington, DC, the company recruited top U.S. designers and engineers, drawing deep inspiration from historic designs by Western Electric, RCA, Klangfilm/Siemens, and UTC. This research-oriented approach laid the foundation for innovative products that honor tube amplification's golden era.
The brand specializes in high-end vacuum tubes, particularly renowned for recreations like the Classic II 300B—infused with the "vintage WE 300B soul"—alongside Blue Glass series in 300B, KT66, KT88, EL34-ST, 6SN7, and 274B variants. It also produces tube amplifiers, speakers, and audiophile-grade capacitors, emphasizing single-ended triode (SET) designs prized for their midrange magic, rich tonality, and expansive soundstages.
Positioned as a niche boutique leader in the U.S. audiophile market, Sophia Electric commands respect among tube enthusiasts for superior sound quality that rivals or surpasses vintage benchmarks, though some note physical fragility in production. With a growing international footprint in Europe and Asia, it appeals to discerning buyers seeking innovative, soulful high-end components over mass-market reliability.
