- Determine Thevenin equivalent for the given circuit

- Relevant Equations
- Basic zeroing and shorting

I am asked to find the Thevenin equivalent for the circuit above. I already got the equivalent voltage by node analysis on the nodes B and A3.

What I'm trying to do is to zero the 10V-source and then calculate the equivalent resistance between A3 and GND.

Whatever expression I come up with, doesn't seem to fit my simulation value, and I guess it's because I'm missing some key point, and the problem seems to be the ##R_{22}-R_{19}-R_{21}## combination, which I am not sure how relates to the other resistances.

To me, R23 is in parallel with R22+R24, but it is not clear to me how this relates to R21 and R19.

Can someone guide me in the right direction?
