6267 / EF86 variant has improved Internal shielding and solid construction.
Against your comp set, A$55 sits above the A$45 75th percentile, so this is a bit ambitious rather than a fair market ask. The spread is not huge, but with a median at A$40 and most recent comparables clustering below the asking price, I’d treat it as an “only if you specifically want this one” listing rather than an obvious buy.
The upside is that this is a well-regarded small-signal tube with a loyal following for its lively, open presentation and strong detail retrieval, so clean examples can be worth paying up for if you need a matching or replacement valve. Since condition is unknown, the main thing to check is whether it’s tested properly and genuinely low-hours; without that, I’d want closer to the median than the current ask.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
JJ Electronic traces its roots to 1993, when Jan Jurco founded the company in Čadca, Slovakia, initially as a modest garage operation within the former Tesla factory. Drawing on Eastern Europe's deep vacuum tube heritage from the Tesla era, it rapidly expanded from producing just three tube types in 1994 to over 40 models today, all developed in-house by dedicated engineering teams. What began with 700 square meters of production space has grown to more than 12,000, reflecting a commitment to reviving and refining classic tube manufacturing techniques.
The brand specializes in vacuum tubes—preamp, power, and rectifier varieties—for guitar amplifiers, hi-fi systems, recording studios, and audiophile applications. Since 1999, it has broadened into electrolytic and polypropylene capacitors, plus a select lineup of high-end tube amplifiers, including four power models and two preamps, all globally safety-certified. These components emphasize durability, musicality, and modern quality control in traditionally handcrafted designs.
JJ Electronic holds a strong mid-tier position in the hi-fi and pro audio markets, prized for reliable, affordable tone that rivals pricier alternatives without sacrificing consistency. Guitarists, restorers, and discerning listeners turn to its tubes for vintage-inspired performance in both live gear and home setups, cementing its reputation as a go-to modern successor to historic Eastern Bloc expertise.
