Centered Tap +/- 9V Walwart

[{ antonio }]

I wanted to know if anyone makes a TRS center tapped power supply. I need + and - 9V and ground for a pedal.

I have search the web but maybe I am overlooking something. 

Thanks for any help!

If such a thing exists, Jameco is a good bet.

However warts with multiple wires are rare. The most obvious technique is to start with 6VAC and use a voltage-doubler to make +/-9V DC.

You need need a bipolar 9v wall wart? Easier and cheaper might be using a MAX1044 or Madbean's Road Rage charge pump board to get you there.

I have a pair of Ault 5712-000-401A wall warts that are ±12 volt 200 mA.  They have screw terminals for -12, 0, +12, spare and ground, so there is no cable attached - you have to make your own.  They are rare, but if you can use positive and negative supplies, they are decent units.  Your other option would be to use two identical wall warts and two plugs on the chassis and using two identical jacks, one with the shell grounded and one with the tip grounded.  That way, there would be no concern about getting the wrong wall wart in a particular position.  Maybe R.G. could design a 2-Spot.
