The speakers needed for this amplifier/oscillator circuit are 8 ohms type, with a size of 6 inches. If it will be used as an oscillator that emits a sound frequency tone, you just ON the pushbutton as it appears on the figure. But if it will only be used as an amplifier, you can eliminate KEY button and C1 switch.

An introduction to Audio Oscillators also known as RC Oscillators. So far, we have considered the oscillators which use L-C tuned circuit that causes a phase shift of 180° due to inductive or capacitive coupling in addition to a 180° phase shift produced by the transistor itself. The oscillators employing L-C elements, called the L-C oscillators, are very popular for …

The circuit is a low power version of a simple power amplifier, and will provide the necessary 3.16V RMS easily using a ±12V supply. Peak amplitude is about ±4.5V, and a simple emitter follower buffer is used to drive the output voltage divider (see below for level control, buffer and output attenuator).
