Hi,
I trying to make a very cheap split power supply. The biggest probelm I have is that the transformers cost a lot of money, but I still need a +-15V source. I can get a 15V DC 2A transformer for pretty cheap, but I'm not sure if it can be used to create split voltages. I came accross the following circuit, but I'm not sure if it is a good design. Can anyone give me some feedback.
Note: This will be used mainly to power op amps in digital circuits, so it should not need much current. The regulators are limited to 1A anyways.
Thanks.
