Brimar ECC83 / CV4004 Box Plate


The Brimar ECC83 / CV4004 is another English made tube readily sought after for its smooth mids and lush sonics. A close second to the Mullard (Blackburn) ECC83 / 12AX7, the Brimar version is fantastic in nearly every application. These have box plate construction with a large O getter ring. Re-marked Colomor 7025 by an old English company, these were originally sold in bulk, so they will come to you in white boxes.

These Brimar ECC83 / CV4004 have box plate construction.

    A solid tube and impressed how it made my V1 socket come alive in my Marshall Super Lead. Yes a little pricey but compared to others at a fraction of the price, it is a great deal for a great tube. I plan on getting another one soon for the V2 socket.
