Electrical – PSpice models for BC547C, BC557C, BF245A, BC548C and BD135-16

modelorcadspicetransistors

I'm trying to make this circuit in OrCAD Capture CIS to simulate it in spice:
enter image description here

I found the resistors and capacitors in the ANALOG library. I also found all the transistors, except Q3, in the TRANSISTOR library but none of them has a SPICE model so i can't make simulations. What can i do?
I found some transistors in the EVAL library but it is not what i am looking for

These models will do the job, just copy them into your EVAL library.
