Hi Peter

This might work but not sure if the connector is the same as the Magicstomp

I have been running my Magicstomp and my Zoom RFX-2000 from a Maplin's regulated AC/DC Adaptor - Model UG010 - for ages - you have to set the output to 12V. No problems at all. They can even be daisy chained but I use separate ones for both units. I always intended getting dedicated 12V adaptors for them but have never got round to it as the ones used are fine.

Phil, the Magicstomp and RFX-2000 PSU requirements are both AC input, so I`d be surprised if you`re using an AC/DC supply successfully. Must be an AC/AC unit

Hi Peter,
Yamaha themselves should be able to supply the correct power supply.

The Maplin power supply, along with other makes, are an either/or depending on whether you want AC or DC. There are multiple connector heads with 2 pins attached which are in turn "plugged" into the end of the adaptor power cable - one way round is AC the other DC. When I first got my Gemini III, I couldn't get it to work on the adaptor as I assumed it would be AC. After talking to David Mitchell I switched the connector head round to DC and it worked fine. I assumed all these pedals that can take a battery used AC but I was wrong in that case. And it didn't seem to affect any of the units if you mistakenly get the pins the wrong way round - which I have done on occasions.

Now let me see who said, "You don't get anywhere without taking risks"? Oh it's the bloke above!!!

[Charlie Hall]

I have to say I am sceptical about merely switching round the connections, as far as I know AC has no polarity and cannot quite understand how switching the connections would produce DC, unless there is something about this power supply that I am not understanding.

The AC/DC adaptor has been around for years. It's not particular to Maplins. I have used other makes on other things in the past - mainly my daughter's toys and games that ate up conventional batteries like there was no tomorrow and you were constantly charging up rechargeable batteries with mind-numbing regularity!

Originally when I first plugged in an adaptor I was in, "I hope this works OK", type mode but now I have no reservations as it's a tried and tested method.

Hi Peter,

The Power Supply for the MagicStomp Mk2 that I have is the KAC-10. The input is 230 Volt AC~50Hz 18W, and the output is 12 Volts AC (not DC), 1 Amp, and is rated at 12 VA.

If you use another make PSU then the output needs to be 12 Volts AC (not DC), 1 Amp or higher, and 12VA or higher. Also it must have (or be fitted with) the correct connector for the MagicStomp (maybe cut off the old one).

Be careful, it is not a DC adapter. Have you tried Yamaha direct?

Hope this helps.

Regards
Roger

Reversing the output lead from an AC adapter merely changes a DC output from negative ground to positive ground. It would make no difference to an AC output except in rare circumstances.

To make an adapter able to supply AC and DC you would have to have either and AC - DC switch, or two leads coming from the body of the unit.
If yours has either of these then you`re right. If it hasn`t you`re wrong.

Different connectors to fit on the end of the cable are simply to accommodate different plug/socket sizes.

Phil, this refers to the conversion of an Alternating Current (AC) to a Direct Current (DC) to replace batteries. It does not also provide an AC output.
Please check the label on the unit. If it has a symbol like this ~ then it is AC output. If it has ~ above -- then it is unregulated DC output. And if it just has --- or ____ it is regulated DC output
--
I`ll conclude this by saying I will humbly apologise, in giant letters, if I am wrong on this matter.

p.s. - I`ve Googled all over the place and have yet to find a domestic adapter that provides both AC AND DC

Hi Everyone

Ian is of course 100% correct about the connector head merely switching from negative to positive ground and has nothing at all to do with mains electricity. I just assume the manufacturers of these adaptors use AC/DC as a generic term meaning they can be used on both negative and positive grounded units. I unfortunately continued to use the same terminology.

I can only apologise for any confusion caused to Peter, who originated the thread and anyone else reading my comments. I can though still confirm that both my Magicstomp and Zoom RFX-2000 work quite happily with these power supplies which are an alternative to using the original power supplies that have either become lost or broken or difficult to replace.

Hi,

I recently acquired a spare PSU for my Magicstomp Mk2 and was pleasantly surprised to find how easy it was to source one directly from Yamaha. What follows is a copy of their email to me:

"Thank you for your email regarding a spare part.

I ordered it over the phone and it arrived in a couple of days!
