Trying to max out my system I connected a 5 Ohm resistor 
between the base of the secondary and rf ground. I scoped the 
voltage across this resistor and found it to be 20 Vpp at low input 
power levels.

Increasing the input power real streamers started growing from the 
brush, resulting in about 40 Vpp across the resistor. From this 
value an effective current of about 2.5 A is calculated and I'm 
wondering when the AWG 26 will become hot.

Non-linearities and surprises all over!
