Till salu är ett mycket fint och matchat par Toshiba 5751, tillverkade i Japan och märkta för Toshiba. Rören är NOS (New Old Stock) och levereras i sina originalkartonger med originalinlägg. Rören är tillverkade i augusti 1963, enligt Toshiba-koden 3H. 5751 är ett högkvalitativt lågbrusigt dubbeltriodrör, utvecklat för bland annat professionella och industriella applikationer. Elektriskt ligger det nära 12AX7 / ECC83, men har lägre förstärkning och är uppskattat för låg brus
At kr 1,500, this is above what a typical used 12AX7 from a normal brand tends to command, but for a Toshiba it’s not absurd if it’s a genuinely sought-after Japanese-made example and it tests strong; compared with a generic current-production tube at this money, the vintage option is the one worth considering. If this is a known-good, low-noise piece with verified test numbers, the price reads more fair than cheap, though not an obvious bargain.
That’s the appeal here: Toshiba 12AX7s are respected for clean, balanced tone, decent detail, and a smooth, unfussy presentation that works well in line stages and phono stages alike. The real upside is originality and good test results, because with vintage small-signal tubes that matters more than cosmetics. At this price, I’d want clear proof it’s quiet, strong, and not a tired pull; if those boxes are ticked, it’s a solid enthusiast buy.

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.
