50 watts transistor amplifier - Another Electronics Circuit Schematics Diagram.

50 watts transistor amplifier

The amplifier and speakers that can handle medium-power is designed to provide a strictly amateur. Accidental overloads can damage the speakers, it is not appropriate for small systems.

What amp settings do not contain an element of the first connection wiring must be careful to work with.
Characteristics of the transistor, the fan or heat sink is cooled enough to find out if you need to focus!

Tech. parameters:
Power: + - 28V
Power: 50W / 4 ohms
Input sensitivity: 250mW of
Input resistance: 50 kOhm
Frequency range: 30Hz to - 30kHz
