Show Variable Grid Leak A suitable set of values for a grid leak would be 1 megohm, 2 megohms, 3 megohms, 5 megohms and 7 megohms. A means may be provided for bringing these values In action, which may be secured by wiring a tap switch so that it may be used to switch any one of a number of grid leaks into the circuit. This will provide a definite, positive value of grid resistance to suit the requirements require-ments of various groups of stations, according to their distance and power. |
