Yes, it is the other way round, the TP are for bias current adjustment which must be done across the emitter resistors. Therefore the white wire mustn't connect to the 4.7 ohm resistor as they are in turn connected to the bases of the OP transistors. Thus the white wire must go to the 0.33 ohm cement resistor, and emitter of the OP transistor
OK - so like I said. I am a bit slow.....it appears that based on what you are saying here John - my connection is already correct? Or do I need to move it?
I note that the black testpoint wire is also connected to the emitters, but I presume these ones are getting the opposite voltage power supply.
I obviously dont want to muck this up.....Cheers!
