You are most welcome. But trust me, making your own excellent quality PCB is really a child's play. I mean even myself, with almost zero technical knowledge, can do it.
I print the design with a laser printer using a photo paper following the toner transfer method and etch it with Ferric Chloride. Then drill with a micro drill. This is all the infrastructure I have in my bedroom lab. And I am really very satisfied with the result. I learned the method from here at DIYAUDIO and watching videos on youtube.
Here is a snap of my recent home made pcb.

I can bet you can make much much better PCBs at home than I do.

And wish you all the very best for your on-going project. Welcome to the LM3886 family.

Thanks Som.

That is a very nice looking board you have there, nice thick tracks, I am impressed!

I last made a pcb back in the early 90s at college during an electronics course I dropped out of due to lack of cash, I had to find full time work sadly.

Identical reason here, lack of cash and also poor health condition. But with the kind help of all of you here I am learning each day, that's the best part of DIY.
When I complete a project/ build- that gives truly professional results, the feeling is priceless.

Strange, I was also quite ill while doing my course!

I know what you mean about diy, I am currently enjoying a 2 chip C moy headphone amp which I built from one of Freds Amps kit's and fitted in an enclosure. It sounds stunning running off a well regulated 12v supply instead of a 9v battery.

Cheers

Davy
