The PCB -It will not be readily available.
U will have to make one for urself.
If u can laser print on a glossy photo paper then read here.

Other method is the good old one.
Draw the artwork using enamel paint on the copper and itch using ferric chloride. In this case go for 3886 as it's easy.
Want pcb layout, there will be hundreds in DIYAUDiO. I have one single sided design here.
Make urself one of this or make more and we will buy if it's good.

I have made a couple of LM4780 and LM3886 PCBs by normal laser toner transfer method (at home) and i offer them for sale in india.
http://www.geocities.com/cool_mechi/lm4780.htm
and
http://www.geocities.com/cool_mechi/lm3886.htm
I will charge 350 Rs per LM4780 PCb and 250 Rs per LM3886 PCB.
Since PCB are home made, it will be in very native form (i.e only PCB with copper tracks, no component layout, numbering etc).
Interested persons may contact me.

Can you give some information about where do I get it for Rs.40.
Sometime back Suraj from OM electronics told me that they are making it, is the one you are referring to.
Oh Man,
It would have saved me lot of pain and many many hours if knew it was available at 40 Rs earlier.Is it still available?😕
Thanks,
Gitesh

Yes, its OM electronics, SP Road Bangalore, Guy at the counter told me that he was suppose to get consignment by first week of May,... but I am worried about the quality of the product and hence thought of buying PCB from one of you.
oh okay, actually for reason unknown it is kept on getting delayed. I spoke to him 2 months back and when I checked last week, it was not ready.
If someone in Bangalore interested, we can get it done new compact design and fabrication. Its not very expensive. I am planning to do it but somehow time has been a factor.
I last week made subwoofer using chipamp and I am so encouraged with results that I plan to built few more amps.
