Just as crystal sets are of two gen- eral types, single and double, or one and two circult sets, so tube sets may be made with either single or double cireuits. And as tbe only real difference between the single or double circuit crystal sets lies in the former using a primary or simple tuning coil, while the other form uses a secondary or induc- tance coil for its circuit, so a single circuit tube set, as illustrated in the first cut, uses a simple primary coil and the double circuit set shown in the second illustration is provided with a secondary or induced circuit. The real difference between the two forms is in the type of tuning coil lned and the consequent variations wiring. Batteries Are mqulred. Ratteries are of course required in using a tube set. As the filament of the tube which throws off the elec- trons requires a very small current and the plate of the tube requires a high voltage current, it is necessary to use two separate types of batterles. i will never be any mistake ould usually have nnected with the rm. but this is not The best rule to The “A" the positive pole rheostat contact an invariable rule. to make the z the attempt advisable t of the sets.
