"Circuit theory: BG1 , BG2 , B1 compose relationship , the direct-current converter , the B1 boosting queen charges after QL bridge type commutation to C2. 3 CT5 lead BG3 , BG4 made up of medium altitude modulus many be settled oscillator big , its output pulse triggering silicon controlled rectifier through. Capacitance C2 goes through 3 CT5 and B2 , B3 , the B4 elementary discharge. Thereupon B2 , B3 , B4 every each other in-line secondary output is close to a ten kilovolt high pressure. While function choice switch K is put in 1 location do illumination flashlight usage. Component choice and fabrication: Transformer B1 uses medium wave magnetic rod to cut out 20 mms and 30 mms after every has often wound a coil two paragraphs, using Araldite glue to compose the mouth form magnetism ring. Every winding data sees that picture gives exegesis or explanation. Use E11 shape magnetism core to compose more well. B2 , B3 , B4 use city to sell the XD type 380 V/6.3V guiding lights transformer , the first time level turns upside down being put into use, 6.3 V of plain secondary connect in parallel assuming elementary series arrangement of 380 elementary , original V rising to assume secondary. Need to pay attention to the secondary electric potential link up each other when linking up, the output voltage is insufficient otherwise. And BG1 , the BG2 beta value respond to greater than 60, the function approaches to the full. Debug: One exchange converter adjusting direct-current first uses B1 secondary voltage above 200 V , should not be lower than 160 V when connecting up 39 k loads. The complete machine links the queen , ZD is glittering, the high-tension pulse transformer issues "the clap , clap " sound. Voltmeter ? E is met in the silicon controlled rectifier sun , the negative electrode room, electricity meter swing maximum value should approach 150 V. Wipe the oscillator oscillating period much responding to with C2 battery charging period synchronism , be that much be settled oscillator pulse arrival triggers a silicon controlled rectifier when should be charged full in C2. This can be to the full synchro by the fact that adjusting R2 , C2 , the C3 numerical value again and again makes the person give consideration to both mutually , in an attempt, to gain the best output. Tune up the queen , high-tension pulse frequency every mark plant in between 60-120 time. ''
