rolul tiristorului este de protectie.de exemplu daca tensiunea de 140 creste aparatul intra in protectie.deci grila tiristorului preia o informatie de pe tensiunea de 140,dar din cite imi aduc aminte mai primeste si de la trafo linii prin vreo doua diode care se mai defecteaza(rezistenta inversa)nu am schema in fata si nici timp sa caut,dar cred ca cel mai bine ai spune ce problema ai la el.
