Hi Rik
Yeah i got a bit confused about this to.
I often use the 2N3904 and 2N3906 but as well i have a supply of BC546
and BC556 (Philips) transistors.
The answer to your question in short is that not all transistors use the
same pin out. To the best of my knowledge they all seem to use the
middle pin as the Base but the Collector and Emitter pins vary between
Manufacturers.
The 3904's and 3906's have E,B,C when looking at them with the flat side
facing you.
The BC546 and BC556 are C,B,E when looking at them with the flat side
facing you.
