Hello all,
I found this schematic online for making a double supply (+15/-15v) out of a single power supply 12v

I made the circuit, but it's not giving me the predicted output..

I measure -0.4V and +10.89 volt.

What went wrong ?

I am not an engineer, just hobbyist. I used exactly the same components as in the circuit.
I checked connections, and everything seems to be ok on that matter


Warm regards

 

To work the circuit would need 12V AC input. It won't work as expected with a DC input.

 

Welcome to AAC!

The circuit requires AC input.
