3115v2 - 1W + 1W Stereo Amplifier Module (LM386)

Uses two LM386N-1 power amplifier IC's for a stereo version of our popular kit 3017 amplifier and has a single dual gang volume control potentiometer.

Ideal for Walkman and other battery powered items. Features independent volume control on each channel and on-board jumper to change between a gain of 20 or 200. Speakers (not supplied) must be rated 3W minimum.
