heh, notice that the original question was about the "power supply that
goes with the 0v train spee dregulator" - so we're talking about lego
transformers, not just any train transformer.

| (...) true - but I think the RCX input is rated 9-12V. I don't have a train transformer here, but wouldn't it be outputing 12VDC? Can't imagine why they'd put a AC to DC converter in the regulator... Anyway, we've used the train transformers many (...) (25 years ago, 23-Aug-01, to lugnet.robotics.rcx)
