The CV53 is a UHF triode designed for grounded grid use. The grid is connected to the flange but is wound on supports attached to the cathode assembly. In this respect it shows the development of the final form of the disc seal triode where the grid is a mesh attached to the flange and the cathode assembly and also the anode are positioned either side of the mesh.

The valve seen from the top showing the folded box section anode. The underside of the box is flat.

The anode dissipation in natural air was 2 Watts. The amplification factor (μ) is 100 and to derive the operating bias the cathode resistor was specified as 150 Ohms.

The electrodes seen across the flange.

The wide glass tube disc seal envelope is 27 mm in diameter and, excluding flying leads is 65 mm tall. The flange is 48 mm in diameter.
