[0-30V Stabilized Power Supply]

Thanks for the reply and the information.

A solderless breadboard frequently causes modern opamps to oscillate at a high frequency. Use a pcb instead.

Since I have the circuit built I am going to give it a try. Besides I do not have a pcb for it. I guess I will be learning how to make my own soon.

So use a transformer.

Thanks again.

[0-30V Stabilized Power Supply]

Hello, this is my first post. I have spent the last month reading most of this post. Thanks for all the great info. My question is... I just finish building this circuit on a breadboard but have no transformer yet. Can the circuit be powered using a 30V bench power supply for testing purposes? I was going to bypass the bridge rectifier and filtering caps and connect the supply to what would be the output of the bridge rectifier. Thanks for the help.
