Till salu ett matchat par Toshiba 5751, tillverkade av Tokyo Shibaura Electric (Toshiba), Japan, omkring 1964–1965. Toshibas tidiga 5751-rör från 1960-talet räknas till de mest uppskattade japanska NOS-rören och är kända för sin höga byggkvalitet, låga brusnivå och naturliga musikåtergivning. 5751 är elektriskt kompatibelt med 12AX7 / ECC83 i många applikationer, men har cirka 30 % lägre förstärkning, vilket ofta resulterar i lägre brus, förbättrad dynamik och en mer avsla
The timing doesn’t really hinge on a new replacement model here; this is an old-stock/used tube buy, so value is mostly about matching and condition rather than generation. At kr 1,195 SEK, the ask is hard to benchmark confidently from the title alone, because “12AX7” is a tube type, not a specific Toshiba series or matched pair claim, and the listing doesn’t clearly state test results or provenance.
If it is a clean, tested Toshiba 12AX7 from the desirable vintage production runs, the upside is real: Toshiba small-signal tubes are often prized for quiet backgrounds, good balance, and a refined, non-fatiguing presentation. For a buyer, the key checks are whether it’s actually one tube or a pair, whether it’s tested strong and matched, and whether it comes from the original era people want. If those boxes are ticked, it’s a sensible enthusiast buy; if not, kr 1,195 SEK is only fair when documentation is solid.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Toshiba traces its roots to 1875 in Japan, emerging from the innovative legacy of Hisashige Tanaka, the "Thomas Edison of Asia," whose Tanaka Engineering Works laid early groundwork in precision mechanics. The modern company formed in 1939 through the merger of Shibaura Seisakusho—Japan's pioneer in telegraph equipment—and Tokyo Denki, the nation's first incandescent lamp maker. Renamed Toshiba Corporation in 1978, it built a storied heritage in consumer electronics, blending industrial prowess with entertainment tech during Japan's postwar boom.
In hi-fi audio, Toshiba excelled in a broad array of categories, from full-size separates like amplifiers and tuners to turntables such as the high-end SR-510, quadrophonic systems, and top-tier record players. Pioneering innovations included the world's first digital synthesizer tuner (ST-910, 1978), the ADRES noise reduction system, and transistor televisions. Under the premium Aurex sub-brand launched in the late 1970s, it offered elite components detached from mainstream associations, later evolving into compact micro systems and, remarkably, a 2018 revival with high-res cassette players.
Toshiba holds a revered vintage-collector status among hi-fi enthusiasts, embodying the golden age of Japanese audio with technical masterpieces that rivaled Sony and Pioneer. No longer a major player in consumer hi-fi—having shifted to energy and infrastructure by the 2020s—its gear remains prized for build quality, innovation, and that elusive 1970s-80s analog warmth, appealing to savvy buyers hunting rare, high-fidelity treasures.
