[QUOTE="Ben78, post: 90552, member: 206"] The TDA2822 shown will put 1 watt into an 8 ohm speaker at 9v supply. Ive been looking for a drop in replacement with higher power output but it seems to be a little lost lamb in terms of standard output pins! I use an amp kit based around LM386 but swapped the IC out for a OP2134 for a bit more grunt and fidelity. That Jaycar kit seems to be pretty good value though. I've been looking at the datasheet and it looks fairly straightforward to mod the circuit to bridge the amp which will give 2w into 8ohm at 7v datasheet - [url]http://hsbp.org/dl667[/url] [/QUOTE]
