Ah, my LED definitely comes on when the heated element comes on but I
can't remember how I got there?

Oh well, I was hoping to find out how you did it. I can think of a few
ways but none of them are very elegant.

Just for you Chris, I took the bottom off my PU-1D and took a couple
of pictures of what I found inside. ;-)

I think (because it's wrapped up in tape) there is a big electrolytic
cap in there as well.

I'm not sure the pictures help but as you can see it's not just a
couple of components but I'm not sure I'd go as far as to call it
elegant (especially the soldering as I was probably supposed to be
'working' when I did it). ;-)
