Hi there...
Oh well, just finished soldering all the parts together, what a mess!!
Thought using a Star Ground like this http://mark.rehorst.com/LM3886_amp/amps_chips_and_star_ground.jpg
would be a good idea.. It wasn't. Loads of extra wire...
Would it be a bad idea if I used a solid copper plate (1,5mm thick, found that @ work) , connected to the Star Ground
and this plate to the Case or would a strip of it fit ?
btw, I went a little to generous with the wire lenght which resulted in some nice noodle salad, guess that's ok?
But i got spare parts...if anything's not working (and i bet there is) I have plenty of lenght to cut out and resolder
Cheers
the more area for ground, the better. you can attach your star ground to a copper plate, then to the case, but try not to make too many paths - things can go bad if ground takes unpredictable paths. just connect at one point, and the plate to the case at one point.
I did the same thing as you and used lots of extra wire; it may cause some extra interference but it shouldn't be a really big problem.
