AMZ Power Supply (Non-Madbean)
« on: July 05, 2012, 06:40:14 PM »
After discovering that certain pedals are very sensitive to power supplies I decided to build one. The board is very customizable. I decided to keep it simple. I have 7 - 9 volt outputs on this. I was going to go with a Duracell copper top theme and changed my mind. The color is the antique gold from Mammoth Electronics. It works great, no pedal hum. Very clean power.

Very nice! I may have to pick one up.

Edit: Ordered one! On yours, are outputs 3-5 and 6-7 daisy-chained? My plan is to have isolated outs for my Strymon pedals and Sea Machine, dirt pedals will likely be daisy chained with a voltage sag option for one or two of them. If possible I'd like to have a dedicated outlet for my XP-100 which I think is DC (so a Road Rage would be used), not sure of the current draw of the pedal though. Also, are you making your own power cables or are you buying them?

What do you use to power it at the input?

When you buy the board you get an email with the parts list and all the mods and suggested power supplies.

This is the one I am using:

Really nice build, i will shortly need to build something similar to that.

Could you tell me where you sourced those DC Jacks?

Thanks for the link Dan, i bought some similar to those from Tayda a while ago but with an external nut, but they don't work....V+ grounds to enclosure when power is plugged in...

Cheers!

The dc jacks can be found at newark, jameco, or banxai music.

Sorry to bring up an old post.. but how is this working for you? Is it very noisy at all? I'm going to build my own power supply but I can't decide if I want to go through the trouble of isolating the grounds on each output or just let them share a common ground. Any feedback would be really appreciated!

It is super quiet. I didn't isolate all my grounds. I grouped 2 sets of two, and 1 set of three. I tried to keep it simple. I only needed a few 9v dc outputs. I don't remember where but I ran across a site somewhere that listed the current draw for lots of different pedals and based my output needs on that.

The cool thing about this design is that it can be configured lots of different ways.

I need to post a new picture of it. I had a buddy laser etch an image onto it that turned out pretty good.

What are you powering it with? I now need to build one for no reason.
Pedal building is like the opposite of sex.  All the fun stuff happens before you get in the box.

I don't see a bridge rectifier, so I assume it's powered with a DC wall wart of some sort...?
