Well, you had a 50/50 chance. Not bad odds. Good old Murphy was there to help.

<didn't work. AT ALL. i'd like to know why.>

The oscillations in our radio oscillators oscillate using positive feedback in the oscillator circuit. The oscillator transformer does this by feeding some of the tank circuit signal back to the cathode or a grid. This signal must be in phase (positive feedback) for the circuit to oscillate.
