Hi
The Acopian supplies may be best but you should be aware that you need a
Plus and a Minus 18 Volts (2 of these units unless you spot a 'dual
output' version).
If you need phantom power then you will need a 48 Volt module as well.
Modules are not very thirsty so for a couple you need only say 500mA.
The chips used in the modules are not happy with much more than 18 Volts
so be aware.
The powerstream was just an index but it is best to steer away from
'switchmode' supplies as unless you get something specifically designed
for analogue audio use (lots of RF filtering) you will be disappointed.
Power one make a 15 Volt 1.2 Amp linear supply which would be ideal.
It's voltage can be wound up to about 16 which will work fine. With a
resistor change they could be taken to 17 or 18 Volts.
You could also consider a couple of Velleman kits which use a LM317
regulator. Get your own transformer (most of which have dual
secondaries) and you would be set up.
If you wanted phantom power then you could easily put an 'overwind' on a
torroidal transformer or arrange for a voltage doubler or trippler to
get the 48 Volts.
