B1 in the circuit is step-up coil and hollow coil, and the primary is 12 turns with the diameter in 10mm, and it provides high voltage for strobe bubble. 220V mains voltage is voltage-multiplied and rectified to provide about 630V operating voltage at both ends of the strobe bulb. Adjusting W1 can change the charging rate of C2, thus it changes the trigger diode CB3 conduction frequency (DB3 trigger voltage is about 20V), thenit can control the strobe's frequency.
