    0-30 Vdc Stabilized Power Supply

    Hey Audioguru. I allready replaced both Q2 and Q4. Before the replacement i did a diode test with a multimeter on both transistors to verify if they had any problems. They had none. No shorts and only two voltage drops. I believe my problem is in this area because the output (pin6) of U2 varies...

    0-30 Vdc Stabilized Power Supply

    Hey Kvakva, thanks for doing the tests. My voltage drop is much higher. When i put a load of 1.5A the voltage drops nearly to 0V. I did what audioguru suggested concerning the voltage in the output of U1. I have a steady voltage of 11V, even under load conditions. I'm almost giving up this...
