go to this sites and browse,

LME49810 and Leach output stage.

http://www.power-amp.eu/power-amp.e/ax1300.htm

http://www.chip-pcb.cn/EN/CP%20home.htm

I use LME49810 to drive a pair of 2SA5200 and 2SC1943, it is good enough for sub. You can add more pairs as required.

I live in Choa Chu kang area. I have no experience in electronics and have not built any amp yet. I am now in the process of building a subwoofer and is almost complete. Now i need to find an amp for it.

I bought transistors ans ICs from shops at Sim-Lim... all parts seem to be and worked as originals... I guess I got lucky!

Sim-Lim is like sin-city for DIY fanatics... looking forward to going back there...

Cheers!
