Thanks for all the input! @Chuck: I assume you are talking about a 100W incandescent light bulb, I like that idea for current-limiting. And I agree a SMPS should cut off the switch if it detects a short; not sure what kind of supply is in there but I'll take a look.
@Patrick: There's a stamp on the unit that seems to indicate it was made in 1984 but yeah the eBayer applied power normally before I got it. Thanks!
