Description

Brand New, MINT NOS mid 1960s Brimar Military Production CV4024 12AT7WA tubes with Black Plates and copper posts. Made in England
by the famous Marconi Osram tube company for the Royal Military.
This 12AT7 is a premium grade, lower gain preamp tube most often used in phase inverter positions in older amplifiers. It is commonly used in a reverb driver stage, but can also be substituted in 12AX7 gain stages where users are seeking lower gain response from higher gain positions in the preamp string. The lower gain output of 12AT7s can expand the range of clip and overdrive potential of higher gain amps for truly authentic roots and traditional styles.
Includes original box, packing and pin protector. Built like a tank!! Many say these Brimar preamp tubes are the best sounding ever made.
Fully tested on a Roetest professional computer tube testing system and double checked for gas with a TV7D/U.
