Till salu är ett mycket fint och eftertraktat NOS Mullard GZ34/5AR4, tillverkat vid Mullards berömda Blackburn-fabrik i England. Detta är den klassiska Mullard GZ34 som av många rörentusiaster och förstärkarkännare betraktas som “The Holy Grail of GZ34”. Mullards äldre Blackburn-produktion är känd för sin mycket höga tillverkningskvalitet, stabila elektriska egenskaper och exceptionellt långa livslängd. Röret har den karakteristiska äldre Blackburn-konstruktionen med svart
For a piece this old, timing matters mainly because surviving examples are scarce and condition can vary more than generation-to-generation value. At kr1,900, this sits right on the recent median and just above the 25th percentile, so it reads as a fair buy rather than a bargain, but still solidly in line with the current used market.
That makes sense for a well-regarded rectifier that’s prized for its sonics and reputation in serious tube gear. If it tests strong and comes from careful use, this is a sensible pickup; the real upside is getting a desirable example without paying a premium. Just confirm it’s genuine, holds spec under load, and hasn’t been run hard in a way that suggests shortened life.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Captain Stanley R. Mullard founded the Mullard Radio Valve Company in 1920 in the United Kingdom, initially to produce high-power transmitting valves for the British Admiralty. Drawing from his engineering background and passion for music, he expanded into audio components, creating vacuum tubes renowned for their reliability and superior sound quality. Acquired by Philips in the 1920s, the brand grew into a dominant force in valves and semiconductors, with production spanning facilities in Mitcham and Southampton.
Mullard focused primarily on vacuum tubes—or "valves"—that powered high-fidelity amplifiers and professional recording equipment, alongside early transistors and audio drivers. Historical products like the 1960s Mullard 510 valve amplifier exemplified their expertise in hi-fi amplification, while their hand-assembled valves became staples in studio and home systems. Though not a modern maker of speakers, turntables, DACs, or headphones, their components influenced entire audio chains.
Today, Mullard holds a revered position as a vintage high-end icon among audiophiles and collectors, celebrated for the "Mullard sound"—warm, detailed, and musical. Reissues and NOS tubes command premium prices in the boutique market, cementing its legacy over a century of craftsmanship amid technological shifts.
