Every element of this thread has been instructive, every suggestion informative.  We all make schoolboy mistakes - goodness I have quite a history of them!  I must say that your level of persistent determination is quite astounding; I would have binned the thing with some unprintable dialogue much earlier in the process.

You can always say that the box with 1703 regulators also fell on the floor, at the same time the 10-100-1k resistors fell...

@ circuit: Thank you for your kind words.    I did just about bin the damn thing, and you're quite correct - it WOULD have been alongside some....colourful language.  

At one point in the thread, it was suggested that I build another board, which I WAS about to do, had my error not been found.  In that case, the 2nd board probably would have worked fine, as for that assembly, I most likely would have used the correct regulator, and would then have decided conclusively, that the fault was something obscure on the 1st board - when in reality, it was not.

I do love a good electronic mystery, but it's a little embarrassing when you find that the fault.....was YOU(meaning me)!
