An electrostatic spray gun having physically integral therewith a power pack for transforming low voltage supplied to the gun to high voltage for application to the gun electrode. The power pack is contained completely within the gun, and includes a combined oscillator and transformer which converts low voltage d.c., e.g., 11 volts, supplied to the gun via a low voltage cable to an intermediate voltage at high frequency, e.g., 6,000 volts peak-to-peak at 45 KHz; and a voltage multiplier circuit which transforms the high frequency 6,000 volt peak-to-peak power to 72,000 volts d.c. for application to the gun electrode.
