Amperex CV492

Hi Folks. My first post. I am a guitarist who has also been a professional radio technician. I have used valve amps and preamps for the last 40 years and don't intend changing that at all !!!
I am underway with some valve amp projects, so hoping to learn and share with this forum.

I have some Amperex CV492, 12ax7. These are NOS ( W German) and I'm pretty certain they are ex spares from Broadcasting equipment.
Amperex 12ax7 appear to be well regarded but I really can't find much information on CV492 (variant ?). My research indicates CV is a Military term for "Civilian use"

I'm interested in people's knowledge of this valve.

regards Bob
