    Thompson is a european company that bought a lot of RCA's assets when they were liquidated decades ago. They did own one or more tube factories back in the day. They might be buying this tube from a chinese supplier, but IDK. I don't think they're associated with Eimac's parent company CPI.

    Yet.

    Thales has become the exclusive manufacturer of grid tubes designed by Thomson, ABB and Siemens in their original version.
    Industry | Thales Group

    Thales (formerly known as Thomson-CSF) is committed to offering the widest, most competitive solution for every professional application. Since 1993, Thales/Thomson-CSF has reinforced its market positions by acquiring the electron tube operations of ABB, Siemens and AEG.

    Triode - Electron Tubes & Vacuum Devices - Richardson Electronics (relltubes.com)

    Thomson(later Richardson) purchased many these facilities when RCA/Sylvania (Phillips) cease to produce tubes...
    Amperex made Some of the best 3-500zg's ever produced in their Holland and French facilities.
