The listing’s “OVP” (original packaging) and “Unbenutzt” (unused) condition implies a near-new product, but the €95 asking price is ambitiously high compared to the typical used market for this JJ Electronic KT88. Based on your ground truth from 20 EUR listings, the median used price is €24.25, with the 75th percentile at €49. At €95, this price clearly exceeds the 75th percentile, making it an ambitious ask rather than a fair or bargain deal. While new retail prices for this tube often hover around €58–€62, paying €95 for an unused item with original packaging still represents a notable premium unless rarity or special matching is confirmed.
The JJ KT88 remains a well-regarded beam output pentode prized for its powerful 42W output, strong bass, and bright highs, making it a versatile upgrade for many amplifiers, including 6550-based designs. Its red glass variant is especially sought after by enthusiasts for its durability and sonic character. If the tube is genuinely unmatched but in pristine, original packaging, there is some upside in timing and condition, but the price still demands caution. Only if the seller can confirm matched pairing or exceptional rarity would this become a worthwhile buying opportunity; otherwise, it’s a case where patience may yield better value.
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.
