Amplifier Modules Parts List

 

Transistor                   TIP120GOS-ND    $0.632    http://digikey.com    Enables low-current from synthesizer to switch high currents through speaker

Volume pot                   CAT# LPF-20K      0.15    http://www.allelectronics.com//index.php?page=category&id=470&p=1&template=    Reduces current into transistor base, makes quieter, run longer

Quadruple Speaker Terminal    24V001    $0.85    http://www.alltronics.com/    Lets power in from rectifier, lets sound in from synthesizer
