Simple low frequency generator on two transistors - debugging the original circuit.
A low-frequency generator from B.S. Ivanov's book "The Oscilloscope - Your Assistant." The video shows a homemade audio generator (signal generator), or more precisely, a prototype generator, assembled to test different amplitude stabilization methods in a simple oscillator with a Wien bridge in a positive feedback loop. The circuit setup process is also shown step-by-step – setup is performed with the feedback loop disabled, that is, without oscillation, in amplifier mode. The video may be useful for beginning radio enthusiasts interested in the circuit design of simple discrete devices, building homemade analog devices and instruments.
