Found some nice transistor tutorials by AllAmericanFiveRadio that seem to be reasonably well put together.
First is one on some biasing basics:
And another still a bit on biasing, but more so on small signal amplification:
One thing I took from this was that it’s good to just get out there an experiment with transistors. It’s one thing to first learn all the theory, but sometime some good ol’ hands on can be useful. I need to go and have a play.
