Power is supplied to the primary circuit through a transformer, which charges a capacitor. Eventually the voltage across the capacitor will increase sufficiently to short a spark gap. The capacitor will discharge through the spark gap and into the primary coil. The energy will oscillate back and forth between the primary capacitor and primary coil inductor at high frequencies

At the other end of your circuit, suppose that you have a HF transformer rectified into an output smoothing capacitor. After doing the safe start, that unit could have 12 Volts 10 Amps going into it. After ten seconds, that has received 1200 Joules, so if it has an output capacitor, it could have stored plenty enough to kill you or start a fire. Burns are an
If you measure the voltage on the capacitor you will see that it charges to a higher voltage than 12. The secondary winding of the transformer is 12V, but that''s a nominal RMS AC voltage. The peak voltage is actually higher, and the peak voltage is what charges the capacitor. If the secondary windings operate at 12V RMS, then the capacitor will

He whacked a big power transformer and some big caps into his amp. Lots of output devices and rated the amp at 50 Watts @ 8 Ohms. Thing is, he had actually built a 75 Watt @ 8 Ohms amplifier. He just told everyone it was 50 Watts. So, under testing, the amp easily managed 100 Watts @ 4 Ohms and 200 Watts @ 2 Ohms. Sneaky huh?
