Any ideas making PS with split rail using xformer with no center tap

Hello there.
Diode-based circuit to take a AC input voltage and produce a DC output, whose voltage is larger than the amplitude of the input voltage.
A voltage clamper is used, the capacitor will charge up, and ind oing so the output
voltage will be clamped to voltage of the capacitor.
Add a second voltage clamper to the first and you get a voltage doubler,
Add another voltage clamper you get voltage multiplier so on and so forth.
You give no specifications, the schematic shows no values for the components. This is only one way to do it.

You could use two inverse connected diodes for half-wave rectification from one side of the winding, giving a plus and minus voltage, with the other side of the winding being common.

IOW, in the #2 schematic, delete C1, C2, D2, and D4. Tie the D3 anode and D4 cathode to the upper transformer point. Leave the lower transformer point connected as is.

Another transformer same type........ parallel primaries, series secondaries.
