Unhappy simple bipolar power supply


how can I use this eschematic (or a simple one like this) to work with a sec. 24-0-24V, 5A transformer and give 30v (bipolar)?

I can't find a schematic to give 30-0-30. I hope someone can help me.

thks all

The schematic is the same whatever you do. All that is different is that for 30-0-30 volt output you need a 22.5-0-22.5 volt transformer, which you will be unlikely to find.

I'm sure a common 25-0-25 volt transformer yielding 33.5-0-33.5 volts will be fine.
