Hi guys, I'm trying to figure out a power supply for my SD twin tube classic. The one thing I need to know is wether its a positive center or negative center tip. That inf is not on the pedal

This is the North American power supply the owner's manual calls for https://www.digikey.com/products/en?keywords=MT7123-ND
There is no mention of polarity there in the specs or the owners manual either.
EDIT:
Here's the owners manual as well. https://www.americanmusical.com/item...x03_manual.pdfLast edited by Mr. 80's; 07-26-2020, 09:30 AM.

It's basically a high gain tube preamp with a built in boost for leads. It also has a switch to change the mid control from being centered on 600hz to 1.4khz. The boost can also run at either +4db or +8db.
I usually run mine into a clean channel with a GFS Twin Overdrive in front of it in case I want to get really crazy.
One of these days I'll try it straight into the power section of one of my amps.

It is 16-volt AC. So, almost any tranny will work as long as it can do 1 amp. But you want to make sure it does a little more than that. Like 2 or 3 amps. You don't want to run a tranny at it's limit.
I also have the Twin Tube Classic. It's one of those pedals that I doubt I'd ever sell. They do something kinda cool internally. They have a 240 volt to 16 volt tranny, wired backwards. So it takes the 16VAC and drives it back up to 240 so that the tubes are run at true HV. I believe that's what gives it the "true" tube sound. It's not a starved plate design, like my Vox Tonelab. (Even though I love my ToneLab.)
But have you contacted Duncan. I did, back when mine went bad, and they just sent me a new Walwart. (If they still have them.)
