Hey Joe & Rodalco,

Thanks for your input. There's just a transformer, no diodes, caps or regulator, and I believe it's an AC transformer because my Fluke meter gives me readings in the AC range but not DC. This transformer is probably 3 or 4 amps, I guess.

I figure it can handle a steady load since it's from a Malibu light system, but I do have another transformer that looks like it's from some kind of musical equipment, and it has diodes, resistors, caps, heat sinks etc. I just want the transformer out of it. A couple of friends had 2 transformers each and dropped them on me, so I'm sitting here with 4 of them.
