The combination Hartley oscillator/step-up transformer shown in A can generate significant negative high-voltage-especially if the voltage output of the transformer is multiplied by the circuit in Fig.69-5B. T1 is a small low-voltage filament transformer of around 4- to 10-Vac output, 120-V primary.
