Vacuum tubes are still being manufactured in the following countries:
China,Russia,United states, united Kingdom,Germany,France,Czech republic & Slovakia http://en.wikipedia.org/wiki/Vacuum_tube...ufacturers
maybe not in the sense your question intended but they are still being made, so the thermionic is still with us.
Back to your question I'm going to say the PL519 line output valve used in colour TV's, it must have been amongst them if not the last, before transistors took over in total.
