+/1 15VDC power question

[Milkmansound]

do you think its possible to get +/- 15VDC and +5VDC from a single 15 (or more) volt wall wart?

 

[PRR]

Use a 10V-12V AC wall-wart and do something clever with diodes and caps. It's done all the time. 9VAC gives about +/-12VDC which is usually quite ample.

 

[Mark Burnley]

Yes,

With a single AC input supply and some diode/voltage multiplier tricks you can do it all. Check this schematic from Rane for some inspiration:
