Mullard 10M ECC81 / 12AT7 Gold Pin Preamp Vacuum Tube
The incredibly rare Mullard 10M ECC81 / 12AT7 vacuum tube is a new-old-stock treasure. Made in Great Britain, manufacturing was at Mullard's Mitcham factory in the mid 1960s. Construction details are gold pin, large halo getter, and small-plates. And to be clear, these are a very different construction than the military Mullard CV4024 preamp tubes we offer. They are not the CV4024 tubes with gold pins.
The 10M tube Master Series was Mullards selected and guaranteed long-life line. At the time, Mullard was stating these would perform well for 10,000 hours or more! They are low-noise and an excellent choice for highend audio, professional audio/studio, and even guitar amps.
Note: These tubes come in original factory-sealed cartons. We will not open for additional testing here. You will get the satisfaction of unwrapping it and seeing it for the first time since it was tested and sealed in the 1960s.
