One thought on “Mullard 12au7 Long Plates []-getter”

1. The Mullard 12AU7 Long Plate with Square-Getter is widely considered one of the top-tier contenders in the 12AU7 family. What makes it truly special is its ability to hold its own against the “slam” and authority of the much larger 6SN7 tubes—a feat where most standard 12AU7s typically fall short.

   In terms of performance, the sound is exceptionally solid and expansive, offering a massive soundstage that fills the room. You can expect sweet high frequencies and a midrange that feels wonderfully warm without becoming “muddy.” However, it is worth noting that upon critical listening, the high-end does seem to roll off slightly early. While this contributes to that signature warmth, some fine details—like the delicate plucking of an acoustic guitar in the background—can occasionally get lost at lower volume levels.

   Finding these gems is a challenge in itself; they are so rare that even finding reference photos online is a task. Be prepared for a bit of sticker shock as well, as they typically command around $124 on specialized tube sites, though lucky hunters might snag them for closer to $50 on eBay.

   Final Verdict: A “must-try” tube for enthusiasts seeking a big, warm, and muscular sound, provided you don’t mind sacrificing a tiny bit of ultra-low-level detail in exchange for that legendary Mullard musicality.
