Hi priest91. Can't get your pictures to open. Try attaching them directly as here,

Too add a photo,
First click "go advanced" in the box below the "quick reply" message box. Doesn't matter if you decide half way through a message to do that, it carries it foward.

Then click "Manage attachements"
Click browse in the first box at the top and find your picture. Repeat for any more pictures.
Click upload... a message appears "uploading"
When complete, scroll down to the bottom of page and click "close this window"

The pictures should now be attached and when you post will appear. I don't think they show in message preview... they never used to anyway.

Make sure your pics aren't too big, a couple of 100k is plenty, and many object when they are massive and it alters the margins
It tells you in the attachments window what max sizes are allowed.

Just set up ONE amp in simple mode and wire that up on the stripboard.
Get it working.

Hi 91

What connections i can see on the stripboard look OK but i cant see any OUT connections .

I have suggestions

make the power ground the closest gound to the negative lead so move c11-k11 to c5-k5 and move the jack socket ground to c7 so the power noise is not going past the signal ground.

Move the positive rail connections from a8-f8 to a19-f19 and a9-p9 to a21-p21 then cut the tracks at f18 and p20 , this will reduce the length of positive rail track that is running next to and in parallel to the input rails and thus reduce power rail noise pickup.

Hi 91

ive been looking at a data sheet on the TDA 7266SA and the pin spacing looks to be half the spacing of 0.1 inch strip board so only every other pin is going to meet a hole......so believe a complete rethink is necessary.

Unfortunately i didn't see the pin spacing.
So, i am going to solder wires to pins and solder the wires into the holes.
Is it safe?

Thanks for the replies.
