ABSTRACT:
A vacuum tube includes a cylindrical cathode around which a frusto-conical control grid extends. The control grid, which is made out of Phosnic bronze, has its larger diameter end attached to the smaller end of a first hollow truncated copper cone. A cylindrical Phosnic bronze screen grid extends coaxially around the control grid. One end of the screen grid is attached to the smaller diameter end of a second hollow truncated cone. The second cone extends around the first cone and is made out of a copper clad alloy of cobalt, nickel and iron. An anode encircles the screen grid.
