2 9V adapters to run 18V pedal?

Is there an adapter somewhere where I can use a pair of 9V barrel connectors to tie into a single 18v barrel?

not quite. I already have 2 barrel connectors from my godlyke power supply. I need 2 female barrel connectors which go to a single male barrel connector.

I don't think that'll work as you intend...you're speaking of the Powerall and the daisy chain? I think if you want to get 18vdc from 2 9vdc sources, you would need two independent sources of 9 volts, chain those to get the 18vdc you need. The Powerall/daisy chain is one big connection at 9vdc. You could do this with two leads off a Pedal Power, Fulltone had a schematic at one point showing how to chain two 9vdc cables to get 18vdc....I'm sure more electronically minded members can give you other good solutions...

Just pick up an 18V. Jim Dunlop has them. Got one at G.C. for about 20.00.

i have one of those. The point is that I would like to eliminate multiple wall warts. I guess I'll buy a DC Brick.

I don't think the DC Brick will do it either, it's also connected like a daisy chain...the Pedal Power outputs are independent and isolated so you could do the chaining like you want...I'm trying to find that wiring diagram...

The Brick has separate 18 V outputs. Definitely search the web before you buy. Some people have had issues using the Brick with certain pedals.

Thanks for the tip. So the voodoo labs is the only option then? What about the new Gator power supply?

You're right...I was locked on the 2 9vdc into one 18vdc chain problem...the 18vdc outputs are on the side of the supply...:AOK (...sorry for the senior moment...)

The problem is that you have to have two separate 9 volt power supplies to do it. You would simply take the positive wire from one supply and tie it to the negative wire from the other. Then you have 18 volts on the remaining two wires. You can't double the output of one 9 volt wall wart into 18.

I bought the godlyke voltage doubler. I was nervous about the noise issues with the Dunlop and the Voodoo labs is overkill and the godlyke has worked power supply has worked flawlessly for me

by the way, the godlyke voltage doubler is absolute crap. Incredibly noisy. I'm going to return it. Very poor recommendation.
