Abstract
The outcome of an experimental study of grid current in currently produced low‐power receiving tubes indicates that if the plate dissipation is kept below 75% of the manufacturers' ratings, the grid current is not primarily due to ionized gas, but to photoelectric emission from the grid under the action of soft x‐rays produced at the plate. A simple empirical formula is given for predicting the grid current from the operating conditions. Data are given for 11 tube types.Keywords
