Log In or Register to post comments Paul Rako on Nov 21, 2016 Well if you add a pot as a rheostat, a variable resistor, it will get you in trouble Check This Out I'm not.
When the voltage across Rsc reaches a point where it can turn on Q2, it will suck the base drive from the output device, thus keeping current in check. Over these parameters you will have troubles and quickly increasing price.
