2.3 Transistor Common Base Amplifier. The common base amplifier is something that you rarely see these days. It was also used in valve circuits and was sometimes called a 'grounded grid' amplifier. Input impedance is very low, and the circuit shown has an input impedance of around 50 ohms. It has high gain, and can be used at radio frequencies because there is almost no …

In an amplifier, a large current is directed through the transistor (in one lead and out the second). The third lead is connected to the weak signal you wish to amplify. When this signal is slightly larger, the switch is closed and the large current flows from lead 1 to lead 2.

The guitar's alternating current audio signal enters the amplifier at guitar input jack 1or 2. 1 is the Hi input and 2 is the Lo, -6dB quieter input. Resistor R1on jack 1 is the 'input resistor.'. It sets the amp's input impedance to 1,000,000 ohms (1M) to boost the signal voltage from the guitar.
