La mine apare in felul urmator :1-colector final linii2-115v3-n.c.4-n.c. 5-masa6 si 10 legate impreuna-filament tub7-abl8-n.c.9-masaO sa incerc maine o inlocuire cu un bsc24 .Am mai facut chestii din astea la alte tipuri dar mai apar probleme la dimensiunea pe orizontala pe care o rezolvi prin modificarea cond. de recuperare si eventual punerea unei bobine in serie cu deflexia.

Daca nu are AFC e simpla inlocuirea.Daca are AFC incearca sa pui o rezistenta de 1K intre iesirea de filament si AFC si daca ai noroc sa fie sensul bobinajului care trebuie merge daca nu faci 3-5 spire pe ferita si tot asa cu 1 K merge la fazare corecta a infasurarii.Iti dai seama ca e sau nu ok imediat daca faza linii e corecta.

Mersi Dan ! Nu are AFC . O sa incerc modificarea ceva mai tarziu ca nu-i urgenta si o sa va tin la curent .
