POG 18V adapter info needed...

    I just picked up a POG cheap yesterday (really used) with no 18V adapter. According to the EHX website they state only use the supplied 18V 500ma adapter included. Don't use other adapters not even other EHX ones. Well, would you use the EHX 18V 1000ma one that is available separately?

    No, I'd use a Diago 18V voltage doubler to take one of the 9V outlets of my power supply and make it 18V.

    Yes, but when checking into power adapters, the other important thing you have to look at is the polarity. The polarity is whether the tip or the sleeve is positive or negative. On the adapter for the POG the tip(center) is positive, and the outside(sleeve) is negative

    as long as the other adapter you want to get is center positive as well, I say go for it

    And if I was Toasted I'd inquire whether one outlet of the Diago can provide a minimum of 500mA even after the voltage has been doubled by whatever circuit.

    it can supply a total of 3A so i guess it would

    Nice catch, Bongo. You're correct - It doesn't work with the POG.

    http://www.diago.co.uk/powerstation_compatibility.html

    It clearly says there.

    Plus, the 18V converter plug that Diago sells has the following spec:

    The amount of power provided is a joke for most 18VDC pedals outside of analog OD/distortion/fuzz, and is well below POG specs. Not to mention, you'd still need another converter plug to get a 2.5mm center-positive barrel to plug into the POG.

    Now, here are the specs on a similar product - the Godlyke Power Pump:

    So, this actually looks like it might work. The current rating is based on 1700mA. The Diago is 3000mA, IIRC. But again, a converter plug for the barrel is needed to get it to fit.

    But before anyone even tries this, there's yet another potential issue to point out... and if anyone recalls my thread on the EHX Bass Micro Synthesizer "Power Pump" experiment, you'll remember what it is:

    See Post #17.

    And for laughs, the thread about my mod attempt as a whole:

    Oh, I forgot to mention:

    In the case of the POG, you would be best off with an isolated-output power supply. The only issue would be whether or not any of the ones currently on the market could provide sufficient current; I think we had a discussion about it before regarding the Voodoo Lab Pedal Power 2, specificially.

    Technically, the wall wart counts as an isolated output... and it looks like you're stuck with the EHX-equivalent wall wart option until someone is willing to gamble with their POG. :ninja:

    Yeah, there are three things "wrong" with the PPII: size, price, and low available amperage. The size and price are worth it to me for what it does, but the amperage thing bugs me often.

    That must be a typo because I've scoped mine and it provides 1.3A.

    Really?

    Hmm.

    There's gotta be a good reason for listing it as a "No" in the compatibility list, though. If it's not current, then it's likely a circuit design thing... in which case, nothing out there is going to work outside of a wall wart or custom-made power supply.

    So, either way... we're back to square one with the POG. :meh:

    Maybe someone could e-mail Diago and ask if they tried the 18V connector with the proper barrel plug on the POG. I'm sure it works alone, if you're right about the current... but in a daisy chain, the POG may cease to work entirely (not to mention, everything else).

    He's from California. It'd be a heck of a lot cheaper to just get an equivalent U.S. adapter here, but with the right barrel plug. The one you show is 2.1mm. :p
