Hi,
I feel a little lazy today, and Mr. Google didn't return anything useful
to my searches.

Can anyone point me to a circuit diagram of an HF amplifier that uses a
PNP transistor instead of NPN?

I know that they behave the opposite, but unfortunately I haven't been
designing BJT amplifiers in the past years and I'm now a bit lost.

I have some spare PNP power transistors with a decent GBW (or ft), and
I'd like to see what happens if I use them as the PA stage of my
homebrew CW transmitters.

Thanks,
