I'm not sure about the "magic number" sentence - I won't think about it any more right now, but perhaps we'll come back to it. I'm trying to keep you focussed on the problem - nothing else.
Let me give you a bit more: if that transistor was germanium (perhaps an AC127), can you see how the 0.3V would result in 1.3V at the emitter?
Yes, it is understood. And the silicon potential hill is 0.6. I'll be sure to refer back to these comments. If it ever seems I am not digesting the info, don't worry, I do file and use these posts. In fact the other day I re-read Miguel's comments on lead identification or may go back. Lately I work at an obsessive level and have been analysing a 2.4+1 superhet as well as the other work I have. Can't seem to switch off. Still in a bit I'll be watching the rest of Planet Of The Apes 1969.
