Hi, Are these nos or current production ? Thanks 

[doogie44]

I see your tube boxes and the actual tubes say SOVTEK, because this is modern New Sensor reissue of the Mullard name from the Sovtek factory tooling. It's said to be a superior Sovtek 12AX7LPS--not a bad tube. By definition it's not NOS and hasn't been made in the English Blackburn factory. Nor is it priced as such here.

 

There's a comparison article (NOS and 'modern' reissue) with tests here:

I hope you don't mind my stating this.
