Potentiometer R1 is used to adjust automatic timing exposure of amplifier lamp, to this amplifier lamp which has 500W maximum power, the adjustable automatic timing exposure is about 0.01~60.00s. If C1 adopts high quality electrolytic capacitor, then the accuracy of repetition timing is higher than 2%. In figure, K1 is 24V AC relay, T1 is filament transformer with center tapped, and it has 12.6V secondary voltage.
