alter PS02 to put out +/- 18V?

[blakbeltjonez]

i need a power supply to power up some modules that require +18V and -18V, along with phantom power, of course...

since the PS02 uses a variable regulator, what would i have to change to make it 18V? i know this is a bit off topic from the N72/A12 application (i'll be saving up my pennies to build a pair of N72's as well) but otherwise the PS02 looks like a really excellent cost effective solution. if anyone could give me some insight i'd appreciate it - thanks!

For +/-18V, change R4 and R5 to 1.6K, and R3 and R6 to 120. At that low of an output voltage, there will be close to 20V across the regulators. Make sure that the current draw is less than 250mA on each side, otherwise you may need a cooling fan.
