diba whenever mababa g2 mo hang muna ang wire ng g2 then saka mo sukatan if tumaas man lang sa board ang problema madalas ko naeeconuter at nababasa na ang high voltage mylar ang problema jan na may 2kv to 3kv po
wala po bang oscillation pag may heater na po at g2  newbie po ako

iyang g2 master. pag meron na yan siguradong may oscillation na yan. iyong sa heater lang talaga ang hindi. may iba kasing mga model na hindi sa flyback kumukuha. dun pala sa power supply.
