Audio level from the transformer is about 100 millivolts which can be connected to a high impedance amplifier or tape recorder input. The 3 transistor amplifier shown above can also be used. For overvoltage protection, two diodes are connected across the transformer secondary to limit the audio signal to 700 millivolts peak during the ringing ...

Transformer coupling permits the input and output im-pedances of a transistor amplifier stage to be matched closely to a transmission line and also allows a certain amount of voltage gain to be obtained through the step-up turns ratio of the transformer(s). Fig. 1-4 shows a common-emitter circuit employing miniature input and output transformers.

How to Build a Relaxation Oscillator with a Transistor
http://www.learningaboutelectronics.com/Articles/Relaxation-oscillator-circuit-with-a-transistor.php
The relaxation oscillator circuit we will build with a transistor and resistor and capacitor is shown below. Below is the breadboard schematic version of the above circuit so that you can see the exact wiring of the circuit to the 4011 chip. First and foremost, we use 12VDC of power for this circuit. Actually any voltage from 12V-15V will work.
