psu and transformer

[electrichild]

Hello,
I realized a 2 ch. mic pre based on the Amek M2500 and I'm going to realize a box togheter with 2 ch. EQ (the Gustav's Calrec one). So I need a psu for both. The mic pres need 48V phantom, their ICs (TL072, NE5534) +/- 18Vcc max, the EQ section ICs (NE5532) too. Total current needed I think is about 500-750mA. Would to use surplus parts, have a 240/22V-1.5A trafo without center tap: can be it useful in some way? 
Thanks for suggestions

It has been discussed before but the link is broken...
Go there:

and DL the MS1B schematic.

That's a +/- 15V, but since it use 317/337 regulators, you can easily adjust them to suit your needs...
