Here I make a stereo power amplifier with IC TDA2003, but actually i made it with 2 IC , so that a stereo amplifier . Construction is very simple and easy. I only need 2 TDA2003 mono amplifier circuit , and then combined into one. see
TDA2003 Amplifier Circuit
Then the transformer , the transformer that i use here is the transformer 10A , so that the power released is greater. Grid power amplifier using the former from the box 10A adaptor , :-) decent can still be used . To view the location of components inside the box , see below :

This amplifier is very good if using a transformer 10A, issued no buzzing sound , and strong for high bass . For tone control using Simple Tone Control Powerfull Bass
cool! im also has make 1 of this, but i just using single tda2003 and make it as small as possible to fit into a small metal case. it work grade but my power supply just only 12V 1A output... . do u have any idea to step-up the ampere without replace the transformer ?
ReplyDeleteno i hav'nt idea to step up the ampere without replace transformer... if you use the 5A is great..
