One thought on “Brimar CV4068/12au7 Long Black plates”
And here comes another superb tube from Brimar. Well… it came from around 1959. Survived and prospered till now. This tubes is fairly different compared to a lot of other Brimar tubes, it reminds me more of Mullard sound with warm mid-range and rolled off top, but the tube is really good – very complex and layered sound as I came to expect from Brimar tubes – especially long plate varieties. CV4068 is a special, military & ruggedized, version of 13D3, which is equivalent of 12au7
