Robodelfy,
The SK1 I got at a garage sale didn't have the wall wart, so I bought
one of those voltage-selectable ones at Radio Shuck. Not to get your
hopes up, but I too inadvertently had forgotten to set the proper
voltage the first time I powered it up. No harm done, whew. That was
before I did any bends though. Good luck with it.
