CONNECTING THE GRID LEAK
The best method of connecting the leak depends on , the valve itself. Some valves work more efficiently with a negative potential, while others require a positive potential. The usual arrangement with a single detector valve is to place* the leak in parallel with the grid condenser and connect the positive L.T. to earth. For H.F. amplification it is generally correct to place the leak between the grid and negative L.T. In mu)ti-valve sets the detector valve has l's leak placed between grid and positive L.T. thus assisting rectification.
