All discreet components and values are the same, the power supply is the same, I’ve double checked the wiring and it should work. I’ve arrived at the conclusion that their are 2 more variables that could cause my problems. I’m using different op amps to the ones used in the video this circuit is based on and I’m using different transistors. These both, however, shouldn’t matter as the transistor is NPN(negative positive negative) so has the correct polarity and as far as I’m aware all op amps should do the same thing.
