gEDA-user: BC547 vs. 2N3904

[Karel Kulhavy <clock@xxxxxxxxxxxxx>]

Do you like more BC547C for higher frequency applications or 2N3904?
I once did a simulation for some Ronja differential limiting amplifier
which showed that BC547C is a bit better than 2N3904 because, despite
it being lazy, it has higher amplification.

Is it possible to get rid of oscillating transistors by replacing the
hand-soldered airwire with a SMD on a 2-sided PCB with a ground-plane?

What is the major cause of oscillations in high-frequency amplifiers?
Inductance of wires?
