I think you misuderstood what Larry said (or I misunderstood what you
said). I think Larry was saying that you should use the wall wart from
the train speed regulator, which is what Lego recommends. Also, I dont
see how you could burn out the diodes in the rectifier.* All the
discrete diodes in the RCX are 1N4002s, which can transmit at least 1
amp. However thay could have used a monolithic rectifier, but I dont
think Lego would produce anything that would fail like that.

*If youve done it, and youre sure thats what happened, then I stand
corrected.

You can do this but it's not recommended. As the RCX 1.0 has a bridge
rectifier on the power input, it's recommended you use a 10v AC supply, to
avoid buring out the diodes.

(...) Yes. That is what I meant. I even believe sincerely that it's what I said. :-) I am not sure who exactly within LEGO first recommended it but if you dig hard enough in lugnet.robotics I believe you will find just such a recommendation.... that (...)
