Hi Sivan

I'm from Bangalore, maybe I can help. I know of some friends here who have built GCs, though my gear is a bit different.

I note you're from Calicut, I'm originally from Kottayam.

hey sivan,

i 'm also in search of LM3886 pcb and from net i got some search results on making PCB at home using Laser printer, copper clad, photo quality injet printer paper and of course ferric chloride just in 30 min. more on net for detail. But so far i have not taken this approch and want some ready made PCB , a group buy would be better than making yourself.digi01 in this forum selling LM3886 PCB for $4 plus $6 shipping from china not bad.
But if we are able to make PCB layout we can manufg. them in india and group buy can be arranged so the cost will be nominal if manufg. in large no. so that many of us without PCB can complete the amp. at nominal cost.

i will make pcb for the project on LM3886 for myself. this will be following the circuit I posted in this forum. this pcb will incorporate the power supply using LM338. the two circuits were posted here:

if people are interested we can make these pcb in bulk and do a group buy.

Hi Sivan

When you don't trust the size of the high current tracks, it is not really good advice to add solder:

Solder has much higher resistance than copper! Better solder a thick copper wire to the high current track, imho.

Approx. 60/40 tin has 10 times higher resistivity than copper.
