And here we go with Brimar again, I got lucky recently and received a lot of superb Brimar tubes. This tube is exceptionally nice, it is transparent, airy, and musical, making it well worth searching for. The biggest issue with these tubes is that there are so many fakes out there, as Brimar brand was unfortunately abused during the later days of tube manufacturing when the brand was stamped on tubes not manufactured by Brimar in the UK. I have encountered many tubes branded as Brimar that were actually made in Russia. One sure way to determine authenticity is to locate the date stamp, though that can be difficult since Brimar is one of the few European companies that did not use acid codes, meaning the stamps come off easily or could be removed by accident. To identify a genuine one, look for a tube with a distinctly flat top, as Brimar has some of the flattest tops in the industry with no creases like those found on Mullard or Amperex. Additionally, Brimar typically features either a square or round getter that is usually quite large.
