ECC81 12AT7WA/CV4024 Philips/Mullard, copper rods, true NOS


2 in stock


Mullard made CV4024, branded Philips 12AT7WA. This is the infamous low microphonics, milspec CV4024 with the copper support rods made by Mullard in their Mitchum plant. The CV4024 is the military special quality, low noise, long life version of the industrial ECC81/12AT7.

Philips owned the Mullard factories and branded the tubes depending on their customers locations and preferences. These were made for the NATO forces and came in bulk crates, so no original boxes. We will supply them with plain white boxes.

Truly great tubes for amp and mic applications. Tested and guaranteed.
