It's the one designated U1 on board.
it's a 78LO8. same edge of the board as the BNC socket between two caps.

After following this thread from the beginning, I have finally succumbed and gone and ordered the oscilloscope and transistor tester kits (with case). I have no idea how to use an oscilloscope and I have only ever soldered one small PCB before in my life. Such trivial details are not significant are they :scratch:? And to make matters worse I've ordered the version that needs SMD components soldering :doh:.

Mr Wilson - you are a bad influence :poke:. Giving people like me ideas above their station. Whatever next?

SMD components eh. good luck with that. :lol: :lol: :lol: :lol:
If you've never used them before I suggest you get a test board as mentioned in a previous post, the're cheap enough to screw up mutilate construct and give some practice.

here's one, http://www.ebay.co.uk/itm/DIY-Kit-SMT-SMD-Component-Welding-Practice-Board-Soldering-Practice-UK-seller-/351548500382?hash=item51d9ec699e:g:V~MAAOSwT6pV36QW

It's all fun I tell you, well that's what they told me anyway. :)

Little 8V 100mA voltage regulator .. Maybe a short cct. somewhere else on the board ??

They also get damned hot as do most regulator chips if you get them reverse connected. :(

I am all brand new to this electronics lark myself , hardly used a soldering iron until I had started this thread :dremel:

PS remember no photos it did not happen :poke:
