What adapter to use for old-style USA bassballs? It's labled "AC" ?

Looking at one used online, but the ac label threw me. It's not dc in? What adapter do I need? Or is it just stupidly labled?
They definitely aren't ac. They run on 9v but (I think) use a jack socket instead. I made ana adapter for mine before I had a normal boss style barrel socket fitted like all my other pedals.
OK, that's easy enough to add a boss sized socket. Cool.
Don't do what I did, get yourself an ISOLATED jack socket as the casing is metal, otherwise weird stuff happens when other pedals tough the casing...
I already made that mistake before, but thanks for the tip!
This episode of That Pedal Show might help, especially the part about polarity.
