NOS Mullard 12at7/ecc81

This is the Famous Mullard 12AT7. We mostly have the CV4024 version. The CV stands for "Common Valve" which is a military designator for the British military. Any tubes that were designated for the military, by law, could not have the factory logo on them. Often, CV tubes would be re-labeled after decommissioning so it is possible to see a factory logo on a CV tube. These are the real deal Mullard made tubes. Some of the last ones left, these are great sounding tubes with that old European heritage.
