How do import a PNP darlington transistor subcircuit/model into QSPICE? The transistor is a MPS A65 (or MPSA65) (datasheet attached). A similar more recent transistor (BC516) uses the following .SUBCKT file
*** From file BC516.lib

How can I import this into QSPICE by pasting onto the schematic in the same way as I do with a .MODEL file? Would this BC516 be a suitable replacement for the MPSA65? Iām simulating a class A headphone amp from a HiFi News & Record Review article from January 1979. I will share this later on but I have to create the schematic first. I hope someone can help. Thanks.
