Dangourous, smart ass comment that will blow up my delay? Filed under 2.Max delay time might be reduced to any place below 0 ms besides the smoke, bad smell, shipping and repair cost.Should be avoided! Seriously.A possibly (??) more safe version could be Originally posted by threm Output: 24V DC 100mA Tip: Positive btw I run mine on 12V - this will slow down the workings of the BBD`s in the DMM and you`ll double the delay time. In a similar way feeding it 8v will triple the delay time and you`ll get about 1200ms. Link to comment Share on other sites More sharing options...

Members Midrange Posted December 4, 2006 Members Share Posted December 4, 2006 So does that mean it wouldn't be damaged by 18 volts?I might have found my way of powering this beast! :love: Link to comment Share on other sites More sharing options...

I might have found my way of powering this beast! :love: Someone else into electronics should answer but what could happen when `underpowering` the DMM is- The pedal will not work but you won`t destroy it- The pedal will get destroyed and not work- The pedal will work but not as intended and you may or may not destroy it.Found on the internett"JustinKwill underpowering a pedal board affect my pedals and/or amplifier? The information I've read seems to indicate that UNDERpowering it is preferrable to OVERpowering it and taking the risk of blowing it out, but I'd like a second opinion. If there's any risk of damaging something, I obviously don't want to continue using the replacement adapter.By the way, the tone seems unaffected."The_Spectacle"I'm not positive if it works the same way when you're running it through a pedal board (though I would assume so), but I know that if you use an AC adapter for a pedal that's an incorrect wattage, it will work just fine at first, but over time it will burn out the pedal completely."Guest"Like spectacle said only a pro knows - The incorrect VOLTAGE or LESS WATTAGE is what kills pedals.When you are talking AC (or DC for that matter) power in this particular instance under power is bad. As long as the voltage (specifically the DC voltage) is the same a higher wattage is OK. You don't want the voltage higher or lower, it needs to be the same. The pedals will only use the amount of power they need. The power supply or wall wart only puts out the amount of watts that the pedals try to use (current draw)The watt rating is the maximum it can put out. "-----------JustinK"Thanks for your responses -- they were a big help. The final word seems to be that voltage and wattage should be the same, and the ampage needs to be greater than or equal to the original (the original was 500 mA, so my replacement is 800 mA to give me a little bit of "head room"). I was able to get a replacement at Radio Shack (of all places!)"-----------Detour DJ"I know this is an aging thread, but here's the real skinny about power supplies: If you read a power supply's specs, it will probably list INPUT VOLTAGE, WATTAGE, OUTPUT VOLTAGE and AMPERAGE. Basically, you can ignore the input voltage and wattage figures because they just describe what the wall wart needs to operate, and any devices designed for American use will need around 110V AC. Wattage for a small power supply like this is negligible.The important numbers are output voltage and amperage. Almost all modern effect stompboxes are designed for 9V DC operation, so that's what your wall wart should be putting out. A little higher (10-12V DC) shouldn't hurt anything, but 9V supplies are so common, why risk it? A low voltage (around 3-8V DC) probably won't harm anything, but it will likely make some effects sound different and some act erratic. Pedals such as Boss or Ibanez use electronic switching, and those circuits need a certain voltage to work right. Still, most effects are designed to deal with 9V batteries that drop voltage as they're used, so they're pretty immune to small voltage differences. Output amperage depends on your effects, but usually a rating of 500-1,000mA is fine for common pedalboards. Figure an average of about 100mA needed for each common pedal times the number of pedals you have equals the recommended output amperage necessary. Finally, just make sure the connector for the power supply is correct for your use and wired with the same polarity as the original. That should do it...

Members gil1 Posted December 4, 2006 Members Share Posted December 4, 2006 threm, maybe you should have skipped the voltage jokes, since there are plenty of pedels that can use voltage tweeks. The idea seems just possable enough since there are ways to do that with some pedals. Link to comment Share on other sites More sharing options...

I might have found my way of powering this beast! :love: Probably not. When I got my Polychorus the guy was powering it on 18v, and while it worked, it was scratchy as hell and weak and distorted and just generally a mess. So he gave it to me for $50. Plugged it into 24v and it was perfectly fine. So no, 18v will probably not cut it for the DMM. Link to comment Share on other sites More sharing options...
Members alteredsounds Posted December 4, 2006 Members Share Posted December 4, 2006 One of my 70's blue ones is running at 14v 'cause the transformer is shot, it will run but gives a new meaning to the words lo-fi delay Link to comment Share on other sites More sharing options...
