Double your voltage, double your fun!
Here is the completed AMZ voltage doubler in a mini-box. To give you an idea of the size, a 9v battery is a little bigger than the green foam pad in the bottom unit.
The camera flash reflected off the metallic particles in the paint and made the finish look weird – it’s not really sparkly like that. There are a few bubbles in the decal, probably because I did not let it dry long enough before going to the clearcoat step. Or maybe because my decal paper is a bit old.
Anyway, the unit accepts a 9v input on one side and outputs 18v on the other. It goes inline between your power supply and any pedal that you want to run off a higher voltage. It is a basic charge pump circuit with a few extra frills that help keep the output voltage clean and hum-free.
Using one of my switching power supplies, I measured 9.0v on the input side and 18.03v on the output under no load.
I did live tests with several pedals in my studio and really got some great new sounds. An 18v power supply can make a simple booster pedal run cleaner and with more oomph… send your amp into interstellar overdrive!
I have a handful of these boards on hand and I may sell a few or even organize a giveaway. I haven’t decided.
The updated pc boards are available here.
Edit: The photo below shows the doubler next to a TS-9 for size reference.
IS the 18V output bi-polar? Could it be used to power some of the old Anderton designs? If so, how would you wire the DC jack in the 18V effect?
This is a very interesting project!
It is only a positive 18v output (and ground). It is made for use with buffers, clean boosts, or even some distortions that can take advantage of the increased voltage supply.
Very nice!
I’d like to buy one now. 🙂
Could you daisychain a few 18v boxes with it?
Could you post a layout and schematic for it? This is a Godsend for making a Mutron III Filter, since it runs on 18v.
Would love to be able to use this with my ada flanger. Would be happy to pay for a board or 2.
Hello! Good Site! Thanks you! qroxcayfibx
Would it be possible to have a layout and schematic for this one? I’d love to build this thing! 🙂
Does anyone or you, Mr. Orman, have a schematic they could share? I would try to buy one but they are apparently sold out and I didn’t see this on the list for the CD. Thanks!
I plan on having kits for the voltage doubler project very soon.

could this voltage doubler be used to make 12 volts 24? either way i’m ordering 2 kits. let me know when you have ’em. (c:

can i power with it mxr 18-volts-pedals?
