    0-30V Stabilized Power Supply

    I'm in New Zealand and none of my usual component suppliers have those op-amps. Like I say, I can get them via mail-order but not in time for me to start building this weekend! I'll play around with the circuit as-is and see what happens while waiting for the op-amps to come from overseas...

    0-30V Stabilized Power Supply

    Thanks again. I notice that earlier this year a guy named Ivan has added some suggestions to the bottom of the original circuit description page. He recommends adding a 7809 regulator and a zener to limit the voltage to the op-amps and connecting the relevant power pins and a couple of other...

    0-30V Stabilized Power Supply

    Thanks for the prompt and efficient replies Holt and Audioguru. If I understand your post correctly AG, the original circuit is fine as long as the hardier op-amps (and transistor) are used. Or, are you referring to the latest version as being the modified circuit referred to by Holt with those...

    0-30V Stabilized Power Supply

    Hi there. I have followed this project for some time and while I think it is one of the better power supply circuits around (hence 35 pages of forum discussion on it), I am still confused as to what the actual outcome of all this discussion has been. I built one based on the circuit on the...
