Why was the smoothing capacitor C1/47 not placed directly after the unit bridge? It was placed in its place in the circuit, where its work as a smoothing filter for the base voltage of transistor Q1 was deliberately stopped, but it works with the rest of the circuit elements. Capacitor C1 is isolated between transistor Q1 and the rest of the circuit by a diode (1N4001).
