This Rangkaian audio Ampilifier is designed to be packed into a mini-speaker box 2, 4 and 8 ohms. This circuit is also equipped with a switch-Bass Booster. can be connected to the output line walkman, mini disc, iPod, CD Player, Computer and other similar devices is its headphone output line.
This circuit of the design without using the IC by using methods that seem somewhat out of date. ampilfier the supply voltage 12v. SW1 switch will produce bass-booster, but at the same time the volume should be increased to compensate for lost power at high frequency.
