Simulation is incorrect

00:51:29

Second transistor base voltage should be around 0.7V not 6.29V

it's the resistance of the BE junction

No, BE connections working like normal diode. It should be stay under 1V.

Sorry... But the simulation is ok. You are forcing nearly 260 ma through the base/emitter junction. While that is a diode, it is still resistive and ohms law is still in effect. Look at the collector/emitter current of the first transistor. ;-)

Now I have changed C,B and E resistance to one 1mOhm and base resistor to 100k. Its look much better now. :)

You are on your way!
