The electronic birds repeller circuit is composed of the pickup amplifier circuit, selective frequency amplifier circuit, trigger circuit, sound effect circuit and the audio amplifier circuit, and the circuit is shown as the chart. Pickup amplifier circuit consists of the microphone BM, preamp amplifier tube V1, resistors R1 ~ R3 and capacitors C1, C2. Selective frequency amplifier circuit is composed of the capacitors C3, C4, inductor L, resistors R4 ~ R6 and amplification tube V2. Trigger circuit is composed of the capacitors C5, C6, thyristor VT, relay Κ. Sound effect circuit is composed of the integrated circuit IC1 and resistor R8. Audio amplifier circuit is composed of the integrated circuit IC2, resistors R9, R1O, capacitors C8, C9 and speaker BL. RI and R2 use the sealed resistors; R3 ~ R1O choose 1/4W carbon film resistors. C1 ~ C3 and C6 ~ C9 choose aluminum electrolytic capacitors with the voltage in 16V.
