What software did you use to recreate this ? It looks very nice.
Hehe, I understand the feeling. 😀
sir question do you have a bridge or have a parallel amp
if bridge please guide us beginners how to:
if parallel please guide us again how to thx miles
A good place to start, for bridged and/or paralleled LM3886, is application note AN-1192:

Thanks... and Yes that's for ATX PSU but for testing only, will move that later into bigger heatsink.
Mr. Mile i wish not to use buffer or preamp and i want it to use direct to ipod, what need to change to increase the gain?
Thanks and regards,
Increase value of R4 (15k) to 33k or decrease value of R3 (1k) to 470R and you have double gain.

i appreciate your pcb work.your pcb are fine in connection that i want a pcb of amplifier 3+3 bipolar transistor 2n3773.with protection circuit .if can do this plz send me that circuit and pcb at my email khan.shahid251@gmail.com

One quick question guys. The PCB n the first post, should be printed just as it is, or should it be mirrored for transferring it to copper?
Since it has text and it's not mirrored, I suppose I should mirror it so it'd then be readable once transferred (and by extension the design usable), but I'm almost certain I'm wrong... My mind doesn't work that well this late in the night.

Yep!... started 2.1 channel With apex LM3886 for speakers and AX-14 For subwoofer

ATX heatsinks are good?
Reading from your posts, i find you used processors heatsinks, so i asume i can use those too? Of course with a 4 in. fan blowing fullspeed all the time?

Processor heat sink for testing with speed controller fan is ok, but I don’t recommend for long term use, but if you accept the noise of high speed blower fan it should be ok.
