Rustbucket Power Supply

[GhostofJohnToad]

Maybe I'm dense.  (Probably am) but is the power supply for the rustbucket a negative or positive center power supply?  Also what have you guys been using since Small Bear doesn't seem to carry the dunlop one anymore.  Also just for clarification it is an AC/DC supply and not AC/AC right?  Thanks.

Still there. It's center pin negative like all our regular power supplies - just 18v.
