# Why don't I get a signal on the load?

I don't get any signal on the load, what am I missing? Shouldn't it amplify the input signal?

I have 50mA from the current mirror, the Vbe on Q10 and Q11 is around 0.75v

• First rule of debugging: look at the intermediate points. Including the input. Figure out precisely where and how your expectation is not being met, then understand why. – Chris Stratton Dec 15 '18 at 15:59
