Build Your Own Clone Message Board

In the attached vero layout I have a question about the blue dot under the IC socket.
I know that the red dots are trace cuts and I see there is a jumper going across that
spot. Does that mean that the jumper attaches there as well?

Thanks, in advance!

I think it might mean that it's a place where ends of two different jumpers meet. You could check this if a corresponding schematic is available. It looks like that chip has pin 4 connected to pin 5, which could well be the case for say the TL072 pin out (or several others that are the same) if the +input of the 2nd op amp is being tied to ground, as you might expect for an inverting op amp setup.

I guess you would have to stuff two wires into the same hole, or build a blob of solder on there for the wire passing by . (I've not yet built anything with strip board, but as of a couple weeks ago I do have some of the stuff ... it's just a matter of time ...)

The IC this build calls for is a LM833. I was thinking of stripping the jumper wire longer and have it lay over to that trace and just soldering it that way. There was no schematic with this layout, but I will see what I can find out on the web. I've only done 1 other veroboard and I really enjoyed the whole process! I am also thankful for this forum. Without it I am pretty sure my pedal building would have stopped at my first build!

Thanks again!

It looks to, to me, to be a regular cut . The IC with about 50% opacity colored it to look blue.

I should have posted the entire picture of the layout I have. After looking at it, the build is described as having "11 cuts and 5 jumpers". Looking at the layout you can clearly see 4 jumpers, the longest having the 'blue dot', so I am going to assume that the dot is where the 4th and 5th jumper connect.

I would agree. Apparently, the circuit only uses one half of the LM833 dual op amp.
