Thanks, Mechans!
I only see 1 line of etched code (with the Heerlen triangle)and the other markings are so faint that even with high magnification, I can see no other lines of code.

I did a search and saw where 1 inmate thought the 12AT/12AX versions had shorter plates than the 12AU7. Don't know if that is true.
