TDA2030 amp

[Stinger25]

Hi,
I've tried to do a layout for TDA2030 amp, and would like to share and ask you guys to have a look and see if they can find any errors.
Also I'd like to know if there's a mod to get -9v/+9v from the bipolar daughter board that Mark posted few days ago.

Here's a link to the schematics:

The layout appears to be ok after a quick once over.  The voltage converter layout I posted the other day is more complicated than you need.  Just use this one to give you the required -9V.

Also bear in mind that I don't think the pins of the TDA2030 have a 2.5mm pitch between consecutive pins like vero requires, so I think you'll have to spread the pins out a bit to get them in the required holes.  Not a biggie but something to bear in mind.

Thanks, Mark,
I think i'll it this weekend if it'll be ok, i'll start to think about a pre amp

I've built it, figured there is an error in the schematics I provided and pins 4 and 5 on the TDA2030 should be swapped.
The problem is, the damn thing doesn't work yet... Double checked the schematics, the layout, cuts, part numbers... Any ideas, guys?

Thinking about building this - your layout looks good to me too.  One question for you - you haven't grounded the tab on the IC by heatsinking it, have you?  According to the datasheet, it's connected to Pin 3 which is V-

Also. . . yes, you're right, the schematic from ggg is wrong, has pins 4 and 5 mis-labeled.  But their PCB layout is right.  So this layout either needs to have the IC pin connections swapped, or have those two rows switched around.  Still haven't built one - thinking I might just make a PCB instead of doing this on vero.  Bending those little legs on the IC makes me nervous.  I've broken them from handling them too much before, they're not very robust where they go into the body of the IC.

No, I didn't grounded the heat sink.
I don't know...
Couldn't make the damn thing to work, no sound at all, just the heat sink heating...

I was really interested in building this as well so i tried swapping the rows and did my own layout, this is my first one ever so please be patient! I was just wondering if this looks correct
