Originally meant to be just an RF buffer, but with a few extra components and higher input voltage, it turned into a voltage amplifier. (A really bad one)
Gain from 2Vpp (TTL crystal) to 9,5Vpp on a 12V supply, Load impedance is around 1Kohm, so as you can see, there is going be another buffer stage.

I also added 3300uF capacitor on the supply, but its glued on the other side.

Note/Update:
As I found out, this was really just a lucky coincidence, because the transistor had a poorly set operating point,
so it caused a lot of distortion with a more sensitive signal (sine wave).
Well, distortion is an understatement; it turned the sine wave into a square wave.
