It is the tonal characteristics of valve tubes that have sustained them as the industry standard for guitars and studio microphone pre-amplification. A transistor amplifier is an electronic circuit that uses a semi-conducting transistor instead of a tube or integrated circuit chip to . The diodes D1 and D2 provides a constant bias voltage for the transistors Q1 and Q2. . fullerotic movies
