Regulated Conditioned Power Strip?

I am assembling a big pedal board with a lot of different effects (Boss, Dunlop, MXR, Vox, homemade, etc...) and have noticed that I am getting some noise from some of the adapters. Rather than getting a bunch of better wall warts, is there a good commercially available conditioner that would work? I know that there are a lot of rack ones, but I would prefer something that I could just have right on my pedal board or something that I could just plug right into a wall. I would like to use just one rather than have to daisy chain things together (I have enough cords tangled up!).  Any thoughts? Thanks.

Sounds to me like you're probably getting noise from loops between the pedals, so no matter how well you filter the incoming power, the noise will still exist.

I think what you really need is an isolated supply for each unit (or in some cases perhaps pairs or quads etc). You may want to look into making a spider supply, which you can build with however many isolated supplies as you want.

Otherwise, you might try using a small UPS, since it's battery buffered, that should keep things nice and smooth.
I like amps etc.

I think you'd like something like this: http://www.voodoolab.com/pedalpower_2.htm eight isolated outputs, each one is regulated.

The spider is basically the same (I'm assuming it's called Spider because it originally is made with 8 separate regulated outputs) buy DIY of course ;)

You're right, I just skimmed through the article on GEO and the first diagram shows a transformer eight secondaries. Each secondary output is rectified, regulated and filtered. Basically what the VL PP2+ is, one difference is the toroidal transformer in the VL unit. There is a multitap transformer at smallbearelec.com, 8 x 11v/300mA , 1 x 9v/2A (I think it is from Ted Weber). That would be great for a Spyder project.

Yes, I just reread the article. Took me a while to find it as I've been misspelling spyder Opps!  :icon_redface:
I'm glad smallbear has one, as the link listed in the article seems to be bad: https://weberspeakerscom.secure.powweb.com/store/magnetic.htm
I believe I'll make one of these next week :)
