I was beating my head against the wall 🧱

I was to make this circuit

So I was trying to set VCE to 12V and couldn't do it.
I started checking stuff finally disconnected the base and could do it

Reconnect the base and back to zero (no matter how variable R2 is turned.

It looks like the 2 trimmers are set up opposite each other, but that should just mean you would have to turn them in different directions, I think it should still work.

Yes sir thanks

My apologies I should have said look for the misprint on the schematic I'm sorry you had to look through the spaghetti 🍝 birds nest on the breadboard.  xP

Now I'm still not out of the woods because I'm gonna have to figure out and explain why that happened when I had it like that  :grr
