FIG. 1.

Detailed circuit for up to 600 V high-voltage amplifier. The MOSFET transistors are Q1, Q3:BUZ80A; Q2, Q4, Q5:BC548C. The diodes are D1, D2:UF4007; D3, D4, D5, D6:DZ 12V. Resistances are given in Ohms and are of 0.5 W except indicated otherwise. Capacitances are given in Farads and have a voltage limit of 50 V, except C10 and C11 with 500 V and C6 and C7 with 1 kV.
