I've got a K8060 and I've managed to get it working after a fault which blew the transistors. I replaced all of them at the same time and managed to get the system up. However the bias can only be set to a maximum of 1.5mV.
I’ve re-changed the transistors but still the same thing. I’ve got + and - 40v at the power supply and also 9V at the 9V point. I can’t think of anything else to change. The diodes are the right way round (D1 and D2).
Can anyone help I’m at the end ofthe road here for ideas… Its going in the bin before long because its taking way too much time and money to keep on with it…
