Nu am cu ce testa lampile!Trafurile cum se pot verifica?Lampile sunt negre la capete!

trafurile se verifica ohmetric , in special secundarele sa aiba cam aceiasi rezistents ohmica,lampile daca sunt puternic inegrite, schimbale daca nu ai tester.

Nu ai osciloscop? Am zis de cateva ori ca poti vedea ce se intampla cu o lampa in cele 3 sec punand sonda pe firul subtire (atentie, firul gros arde sonda, eu am patit-o chiar daca am pus un divizor cu 3).
