Yaqin’s integrated amps have a solid reputation for big, lively tube sound and decent build for the money, so A$590 in excellent condition reads as a fair-to-strong buy rather than an overreach. I can’t pin down this exact model’s usual used range with high confidence from the title alone, but comparable Yaqin integrateds often sit well above this once landed and working properly, so this asking price is comfortably in the buyer-friendly zone.
What makes it worth a look is the usual Yaqin appeal: good midrange presence, a bit of tube bloom without totally softening the presentation, and enough wattage to enjoy efficient speakers in a real system. If it’s genuinely clean, well cared for, and comes with the original tubes, remote, or box, that adds real value; at this price, I’d be more focused on confirming quiet operation, healthy output tubes, and any service history than on haggling hard.

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.
