hello I made the original power supply(30V 0-3A) with all the original parts.( http://electronics-lab.com/projects/power/001/index.html ) I have the maximum output of 11.5V!!! and the led is always on. The voltage after the bridge is 33V dc. I measured the reference ( pin6 to pin4 at U1) and I have 10.6V (I disconnected the P2 and P1).After this i disconnected the D9 and I measured the voltage at pin 6(u2) and is 0 to 11.5V depends of P1. All this measurements was made without load. Please help me
