hello,
I have a 24V DC 1A regulated power supply and when I have it hooked up to a bread board with 2 1k resistors in series between the inputs and the middle hooked up to earth I get +\- 12V. But when I connect the rails to the active filter they change to -7V and +14V :bawling: Has this happened to anyone before or does anyone have an idea on what maybe happening?
Cheers

| Did you buy that power supply thinking you would have a good supply for the active filter? Where is the schematic of the filter for us to look at? |

| The problem is that your "ground" is a rather high impedance, buffer it with an opamp in unity gain, non-inverting mode. |
