thank you for this contribution, and just the last one :
Have you created the LM4780 component yourself?

I suppose I will change your pcb for me, but thank you, it's more simple to begin with a model.

I'm confused about the printing of the eagle files. I have the files and I have the software, but I can't seem to get the pcb printed properly. I'm missing the earth-copper connections and I can't seem to get rid of the silkscreen. Could someone convert te image, which I should print, into a printer-friendly-format such as pfd?

Yay, Eagle files! You can read our minds! Tis is going to be my next DIY project!

I was waiting for something like this to come out and or be made. I tried to make one of these pcb layouts for the LM4780 but my board layout wasn't very popular.

I see no flaws in your work whatsoever.


GOOD JOB!

SuperR, to get the groundplane you have to click 'ratsnest' or type 'ratsnest' in the commandline.
Then the groundplane will be poured in.
To get rid of the top-connections (wire-bridges) and silkscreen
go to 'view' , then to 'display/hide layers' .
deselect layers 1 (top), 21 (tplace), and 22 (bplace). Then choose 'OK'.
Now you should have your board as it should be printed.

When you choose 'print' , select 'black'.
This way your pcb will be printed in black.
When printing make sure the scaling (dimension) turns out correct.

Hope this makes it clear.
If you have any questions or if you dont succeed drop me a line.
(i can also export to bmp for you)
edit: make that to pdf

Groeten,

Klaas

I take that back ..

What's up with the input resistors? They're different values for each channel!

Left/Right balance is going to be off this way.
