Default P88 preamp power supply

Ok so im having a go at rod's preamp project 88: http://sound.westhost.com/project88.htm

I want to build the unit as a self contained unit including the power supply. My question is can anyone recommend a nice stable, mains powered, PSU for this project which i can include in the box with out the needs for a wall transformer?

Wound i be able to use this PSU design http://sound.westhost.com/project05.htm And just include a 16v transformer wired straight up in the case with the mains connector on the back?

Any help is appreciated.


Thanks for your time,
Scribble

I didn't read through all that article but if you just need a +/- 15 V PSU then here is the one I made:

Hi,


You can use the P05 preamplifier supply with no problems at
all, and you can put a 16 - 20v transformer inside the box,
just make sure it's placed far enough from the preamp.
If this is not possible, that u can put a buffer between the tx
and the preamp (piece of metal, etc.).


Udi.
