[0-30 Vdc Stabilized Power Supply]

And yet another question from me :)

I'm designing a PCB for the PSU at the moment, but there's something in the schematic that's not entirely clear to me.

On U2 there are 2 pins that do not have a number next to them. I figured that it shoud be pins 1 and 8, but i just wanted to double check...

So can anyone confirm this?

anyone?

Just to be sure:
If I change the circuit to the one I've attached It would measure Current instead of Voltage right?

Edit: I need it to measure 0-3A

Is it possible to use a 2N6578 instead of the 2N3055?

I was aware of that.
I was a bit confused about pins 2 and 3, but i guess i dont even need those two.

Hi, i'm thinking of using this cap as C1 but I'm not sure if its a good one for this project.
Some pictures:




There are four pins at the bottom, 1,2,3 and 5. The arrows for indicating the negative side are pointed towards pin 5.

My question: can this cap be used as C1, and how do i connect it (what pins do i use)?

thanks.
