Referring to Figure 1, there is shown a phase controlled, regulated power supply which is relatively insensitive to rapid power fluctuations occurring in an AC line source. As shown, a 115v 60Hz line voltage is applied to conventional DC bridge rectifier 20 which includes four diodes 20a, 20b, 20c and 20d, connected as shown. Rectifier 20 converts the applied AC power to full wave rectified DC power across the output leads 22, 24. The output on lead 22 has a 12Ocps ripple component which is filtered by a circuit comprising capacitor 26, zener diode 27 and resistor 28. This filtered DC voltage is then used to provide power along lead 25 to the amplifier circuits and a biasing signal to circuit 60, as will be seen.
