Hi,
I'M attempting something quite ambitious and I need some advice.

I'm built 16 LM 386 as amplifiers linking all the gnds together. What i get is hiss sound and distorted signals. Building 2 on a board is alright, no hiss nor distortion. How could I rectify this problem?

I know that this is mainly for Lunettas but I don't know where else to ask for help. I hope someone can give me some advice on this.

any help please?
