Hi
I m from Kolkata, India. I want to assemble a LM3886 based stereo amplifier system with Bass Treble controll. Can someone please suggest good amplifier kit, PSU kit & BT kit available in India.

Theking,
did you notice the last three sentences in the description.
"Use a 60W light bulb for first start up and then replace with a fuse".

That's the first time I have noticed retailer using our Forum for basic research.

Tried to separate power ground , output ground (OGND) and signal ground.
Any adivice to optimize this layout?
