Diptrace tutorial youtube2/24/2023 ![]() ![]() ![]() "Improving Williamson Amplifier", Talbot Wright ![]() I modelled Williamson upon suggestion from articles Of course, inductance is not constant, and there are other parasitic parameters like stray capacitance, yet they are vary from one model/manufacturer to another, and with ideal model you can check problems with tube/transistor circuit alone. Then, if necessary, adjust coupling factor according to measured leakage inductance: Even with that model, results of simulation are surprisingly close to reality. Coupling factor 1.0 corresponds to ideal transformer with zero leakage inductance. Ln) with inductance value in Henry, and link them with coupling factor (K1 L1 L2. Put necessary number of inductors (L1, L2. The small secret is you don't need to create output transformer model (at least in this particular case) ![]()
