Rocktron adapter info

[Force666]

Hey guys, I need an adapter for a Rocktron Hush Super C rack. I have all the info but one thing.

I need to know the polarity of the jack.

I know it's 9VAC , 2000ma, 2.5mm jack....just need to know the sleeve/tip polarity.

The same adapter as: Xpression, Blue Thunder, MIDI Mate, All Access, Banshee, HUSH Super C, Gainiac 2, Intellifex

Much appreciated.

I used to have one, had a missing adapter, so I built my own. I'm almost 100% sure that the outer part of the jack is -, and the center post is +. That's how most of those work at least.

But I forgot to add, it shouldn't matter anyway on that side of the wall wart. Either way would work. The circuit won't care(think of it like wiring a speaker backwards, still works the same just flipped phase)

It's 9v AC, Alternating current, so it doesn't have polarity (or rather it's changing constantly). So either way is fine

Thanks guys, that makes sense. Appreciated!
