help with power supply

ok, i got a ring mod through ebay. so i set it up and i notice the power supply is not the moog issued one. so this one says on it, imput: 120vac 60Hz 5.5W. output: 9vdc 300mA. ok, now i noticed some slight distortion going on. are those specs right for the unit?

I own 3 Moogers: MF101, 102, and 103. Two of the three came new with non-Moog power supplies. The two that don't have the Moog logo are both "Ever Glow". One is 9v 200mA and the other is 9v 300mA. The "Moog" power supply is 9v 200mA. I don't remember which Mooger came with which power supply, but I've used them all interchageably. I've noticed some hum and distortion on the MF101 only, regardless of which PS I use. It usually seems to have more to do with what power outlet I'm using, what amplification I'm using, and where the Mooger is in relation to other electronics/power and audio cables.

I would be very careful not to use any power supply that wasn't original to the Mooger. Based on my power supplies, I would look for a 9v with between 200 and 300mA. I think it would be unusual, but not impossible, for another non-Moog 9v adapter to damage your Mooger. But, it's probably not worth the risk.

so those specs that i wrote are ok then? it shouldnt damage it?

Those are the same values as my ps.

i need some help:

I really hate adapters, they're extra crap to worry about and they take up space on my powerstrips...i have 3 moogers and 3 adapters.

DOES ANYONE KNOW THE POWER DRAW OF THESE UNITS SO I COULD POTENTIALLY DAISY CHAIN THEM OFF OF ONE OR TWO ADAPTERS?

And ideally, does anyone know how to power these up with a Dunlop DC Brick multipower supply? Thats the one I own but it wont power moogs, i need a converter or something.

please help

I have 4 mf (101, 2, 3, 4SD) running off one daisy chain. The adaptor is an old boss, it looks pretty big and would probably give 500mA @ 9VDC.

It would probably be a good idea to email Amos and ask him the draw of each pedal. (When you approach the current limit, you start to draw off the mains, and that's where the 60-cycle hum comes from.)

The Dunlop Brick uses negative tips on its supplies. You need to use the red wires that come with it (which have opposite polarity) or else buy a few parts and wire from Radio Shack. So take a 2.1mm in-line DC socket and connect it to a 2.1mm in-line DC plug, but wire the tip to the ground, and the ground to the tip. Enjoy.

i'm embarrased to say i have no idea how to approach doing that, ive never done anything like that.

I use one of these to power 5 foogers and a cp-251

http://www.stompin-ground.com/products/sgpowerall.htm

need to get the Red adaptors to reverse the polarity. They say you can chain and power up to 20 devices on one plug.

so as opposed to buying the whole powerall system, could i just order 3 red jumpers? they need to have a male 1/8inch end to plug into the dunlop dc brick, or a female barrel plug end to plug into one of the included brick cables.

IF you use one red first, then put the harness extension.. you only need one.. everything after that will be reversed. If you are willing to cut and splice yourself, you don't need the red one- you can flip it yourself.

Ok so a red cable and then like the daisy chain deal to the 3 moog units.

I'm afraid of over drawing the brick or underpowering the moogs however,

the brick says it has 375ma of current in the 7 9volt jacks provided....i have nothing plugged into the 18v jacks of the brick, possibly some power could be diverted from there.

i have never cut and spliced to switch polarity, is it just switch two wires around?
would rather just order these cheap cables and get it done.\

thanks for any info you can give me and what you've already told me

oddmusic, thanks for the link, i called stomping ground and they were very helpful...still unsure about overdrawing the brick though.

ok so i purchased 3 red jumper cables from stomping-ground.com.

they switch the polarity coming out of my powersupply and they work. however i have yet to power all my pedals with my power supply because I'm afraid of overloading it.

Again, its the Dunlop DC Brick and the website says:

even 9V outputs can handle an average of 55 milliamps each, or a total of 375 milliamps in any configuration Three 18V outputs can handle an average of 208 milliamps each, or a total of 625 milliamps in any configuration All outputs may be used simultaneously for a total power output of up to 1000 milliamp

I've added up the milliamps of all the pedals i have daisy chained into one of the DC bricks 9v jacks and it adds up to about 100 when my tuner is on.

I have 3 mooger fooger units, as i understand, they require about 250 milliamps each, I know the DC brick can power up to 1000, but can ALL of that power be directed to the 9volt jacks? Or can they only handle 375?

Let me know if you know. I don't want to fry anything out. Thanks.
