With the simple transformers used the capacitors required to tune the circuit to 470kHz would be around 3000pF. You can either place it touching a track block, or connect it with Railcraft wires and power will flow into the tracks. RF transformers are widely used in electronic circuits for: Impedance matching to achieve maximum power transfer and to suppress undesired signal reflection. By placing an RF Choke in series with the Plate/B+ circuit, we effectively permit the DC component to pass, but restrict the AC component (remember that RF is simply high frequency AC). The twisted pair of wires provides the necessary coupling and forms a transmission line. In radio frequency applications there are many techniques to choose from. In some SMPS designs current transformer (usually made using a ferrite toroid) helps to track the current in the control circuit's feedback loop. Transformers and coils There are many electronicians, both hobby and professional, who are at war with electromagnetism. The goal is to match inductive or capacitive loads to a 50Ω line or source.
