The Brimar 6SN7GT Gray Round Plate is truly an amazing find for any audiophile. It delivers a sound that is open, transparent, powerful, and incredibly dynamic. While many enthusiasts often overlook Brimar because the brand wasn’t historically imported into the US, this “neighbor of Mullard” consistently proves to be a step up in quality and performance.
The listening experience is where this tube truly shines. It creates a huge soundstage and a life-like image that is very difficult to match, making it easy to see why it has become a personal favorite among all tube types. It is one of the few tubes that stops the “tube rolling” cycle—once it’s in your system, you simply won’t want to take it out.
Among collectors and serious listeners, the Brimar 6SN7 is widely considered to be a “Holy Grail” of 6SN7 tubes, sitting firmly on the same level as the legendary Mullard ECC32. Most of these high-sought-after examples were produced during the late 1940s and throughout the 1950s. Production was primarily centered at the Footscray factory in Sidcup, Kent, England, which was the main manufacturing hub for Brimar (under Standard Telephones and Cables Ltd) until operations eventually moved in the late 1970s.
Final Verdict: Highly Recommended. If you are seeking something special that offers a legendary 3-D midrange and spaciousness, seek this tube out. You will not be disappointed.
Brimar is a member of BVA, British Valve Association, along with Mullard, STC and GEC. Brimar is relatively unknown in the USA but made some truly outstanding tubes. The Brimar CV1988 is one of their most well known tubes here in the USA; it is an excellent 6SN7 type with an engaging, textured, 3-D midrange that rightly makes the CV1988 a hifi legend and one of my “go to” 6SN7 tubes for any application. Less well known are the EXCELLENT Brimar CV4004 UK milspec ECC83/12AX7, and the 13D5. Type 13D5 is Brimar’s fabulous premium-version, factory selected-stock 12AU7. Especially well-suited for linestage preamplifiers, the 13D5 offers an almost 6SN7 sound in a 9 pin format and is an excellent choice for octal tube lovers who have a piece of equipment that requires a 12AU7. Brimar’s 13D5 is known for consistency from tube to tube, a sign of tight quality control, and sonically it is rather neutral yet layered and spacious in the upper midrange; a real winner that is still very much affordable. Brimar’s CV4004 is a decent sounding ECC83 type, but it was never made in very large quantities and thus typically costs $80 to $110 for a single tube…and for that kind of money, there are better ECC83s out there. However, with the CV1988, 13D5, and the legenday Brimar “T” labeled audio tubes (T for TRUSTWORTHY! A series of factory-selected low noise, high Gm, low microphonics hifi tubes) Brimar is a tube company well worth learning more about. Oh… and about those great “T” series tubes; the T6060 is one of the very best 12AT7s ever made! If you use 12AT7s, “Trust” the quality of Brimar’s T6060!!
