Attached is a circuit based on discreet BJTs in a differential amplifier configuration, with a current mirror load, simulated in PROTEUS.
I cannot understand the voltage level at Q2 Collector which is 53 volts while the VCC supply is 9 volts only. These voltages can be seen displayed on the DC voltmeters on the right side of the circuit.
Help much appreciated.
