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.

    These are a wonderful sounding tube. I used it in a Marshall DSL15H amp in the V1 position (metal can) and it really mellowed out the ultra gain channel and sounds melodic and more 'marshalley".

    These are far superior to the sino at7 and the jj at7 in my amplifier. The amount of detail retrieval is amazing as well as the "musicality".

    I used this as a phase inverter in my DRRI and it did improve the tone relative to the JAN Philips AT7 I was using (and had been happy with). The difference was a bit subtle, but definitely audible. The Mullard tube made the amp sound a bit sweeter/more beautiful.

    I play these in a Vox AC15 thru a Heritage 535 with Duncans, Jazz in Neck and Special Hot AlnicoV in Bridge with treble bleed & 500 K pots! I've used the Black Sable Cryo preamp tubes and they're great but the gain is such I need to lower amp volume to clean it up. These Mullards fit my Pups and I can crank the amp to let the Power Tubes (Telefunkens) do what they do best. I use guitar volume to moderate the input and it's awesome... lush overtones clear present highs and overall very warm! Try a set and depending on your guitar setup and amp don't overdrive the input with High gain pre-amp tubes: that's what Power Tubes are for!
