ODDS AND ENDS.
Always see that the H.T. supply to your set is completely cat off before inserting a screwdriver, cr" carrying out any wiring alterations.
When a set is changed to short -ware working it is often an advantage to change the value of the detector leak to a greater figure to increase sensitivity".
The purpose of a grid-bias battery is to adjust the initial potential on the grid of the valve relative to its filament. No current is supplied by it.
The resistance-capacity method of couplies two valves together is generally con sidered best because the voltage drop across the anode resistance is independent of the frequency of the anode currents.
If vou suspect the insulation of an L.F. coupling condenser try disconnecting the H.T. from the preceding valve plate, when a decrease of anode current in tie following valve will indicate a leak existing across tie condenser.
