Its use w^as limited, however, by the diffi- culties of maintaining a constant degree of vacuum and of providing a suitable source of high voltage, as well as by the general bulk and clumsiness of the apparatus. We have seen that in the nearly thirty- five years since the first invention of the tube, many improvements have been made both in the structure of the tube and in the methods â 'nVatson Watt and Herd, Jl.
