I collected my old component rack from my mum’s loft a couple of weeks ago and in one of the drawers I found two pieces of breadboard with the same thing built on each of them. I built these when I was in my early teens and that’s quite obvious from the quality of the soldering. The amazing thing was that they worked and actually worked quite well.
Here’s a picture of the two dusty boards.
I think there are 2 x BC107s and a BC108 in there but it’s quite difficult to tell.
Would anyone (except my brother) care to take a guess as to what this board is?
