Question about powering pedals, voltage, and noise.

[wickenspoet]

Okay, I'm sure these are stupid questions, but I don't know much about voltage or the difference between AC and DC or different voltages, etc...

Can the Seymour Duncan Tube Pedals be powered by anything other than the 16 volt AC adapter they ship with?

Also, if my other pedals run from the 9 and 18 volt inputs from a Dunlop Brick, do you think the 16 volt AC power source cause any unwanted noise?

Please forgive my ignorance. I'll go back into hiding now:flush:

Re: Question about powering pedals, voltage, and noise.

I believe the Brick is DC only, plus with the voltage mismatch you couldn't power the TT. Voodoo Lab makes a Pedal Power in AC, but I can't remember how adjustible the voltages are.

The basics to remember when finding a power supply are:
-AC or DC output
-Center neg or Center Pos (You can get an adapter to switch)
-Voltage output (in some cases a higher or lower voltage is OK, but it's best to match the pedal input voltage to the output voltage of the adapter)
-Current output of the adapter must be equal to or greater than the current requirement of the pedal. (A lot of the tube pedals draw a lot of current) If you are daisy chaining, it's the sum of all the current requirements of all the pedals. (I burned an adapter by overloading it)

I've never daisy-chained AC pedals, most of mine have different plugs and voltages except for a few 9VAC ones. When you daisy chain DC pedals, make sure they are all center neg or center pos to avoid damaging any of them. If you get noise, it's probably the daisy chain, some of the digital pedals, especially Line 6, need dedicated power supplies to stay quiet.
