I have different issue with this same kit , bcz my output voltage can't be adjustable , and also voltage across the r1 is 30-32 vdc and the resistor r1,r2 are heating , then my transistor voltage on 3 terminal is 30volt dc , pls help me
But the voltage across C3 is also low. Either that negative rail is not being generated correctly or it is overloaded.
Also I can't see how that would drive the opamp outputs to 30V...
Yes I read it , now I found a new resistor with heating up r15 also heating , I so tensed because this board working good in last days I don't know what happened to this
