Lonerider Posted January 10, 2022 Share Posted January 10, 2022 Va salut. Am un autotransformator АРБ-400 "ЛЬВОВ-3". Nu a mai fost folosit de mult, stiu ca avea tubul indicator slabit (probabil), pentru ca mai utilizam un voltmetru de verificare a tensiunii de iesire. L-am desfacut, dar nu se vede nicio indicatie pe tub. Din poze, imi puteti spune/recomanda ce tub este si cu ce sa-l inlocuiesc? Multumesc. https://postimg.cc/gallery/nhSJfMS Link to comment
Усилитель Posted January 10, 2022 Share Posted January 10, 2022 (edited) Este in-9, rusesc, nu are inlocuitor. Se mai gasesc. Pe la 15 lei gasesti voltmetre noi CA : 250 V, e mai usor. Cam 5x5cm.sau digital. Edited January 10, 2022 by Усилитель Link to comment
