TDA8920BJ amplifier PCB Have been found and done.
 
Today i had simple yet good sounding and stable class D amplifier in my mind...
So i ordered 5 pcs of TDA8920BJ chips...
Then... for ... sake i dint even find schematics or any pcb...

Has anyone pcb/schematic for these chips, must find stable way.

If no one has, i will create one.

Thanks.

Today, in silent down in poland, they made this:

No smd parts used, only thole, great for guys who have lil shaky hands.
I think design seems great.
Going to make .PCB so there would be something in google....

Or you could just buy a SE-FX60 Panasonic wireless rear speaker and use the power supply and TDA8920BJ amplifier board out of it.
Or modify it to work without the receiver enable for the music port like I did.

does anybody have a ready to print pcb on pdf or something like that...
i want to try building this amp a long time and i can't get a pcb like the one in the firs comment, with no smd component that are very hard to get in my country (i'm from argentina, so, i apologize if i write someting wrong, but you'll get the idea...)
and... thank you
