Single rail and dual rail PSU on same transformer?

[Mundox]

I am trying to rack some pres that need +24, and +18/-18, as well as 48V.
The mic input card needs the +18/-18/48V and the line driver needs the 24VDC. The cards will be isolated via output/input trannies.
Is there a schematic you know of that achieves a similar output, say from a 24 0 24 transformer.?
Or should I just use 2 separate power transformers?  :'(

Thanks for any input!

Vedat,

I am not sure what sort of power you need but I have  the following multitap toroidal  in 150VA and 216VA versions which may make your life a bit easier;

Primary 1:  0 - 115
Primary 2:  0 - 115

Secondary 1:  0 - 17.5 - 25.5
Secondary 2:  0 - 17.5 - 25.5
Secondary 3:  0 - 17.5 - 25.5
Secondary 4:  0 - 17.5 - 25.5
Secondary 5:  0 - 53
