Va salut,Am 2 filtre provenite din niste boxe electronica industrial, nova 1. (poate va sunt cunoscute)O boxa imi arata impedanta 10 ohmi (in loc de 8). Boxa ei pereche arata 7.9~8~8.1 ..ceva de genul dar oricum foarte aproape de realitate.Acum ...din cate am inteles s-ar putea sa se fi dus condensatorii din filtru sau rezistentele corect ?Daca la condensatori o sa fie o inspectie vizuala (umflat , spart, scursi etc), la rezistente ce imi recomandati?Daca iau multimetrul si il pun pe ohmi...fac bine sau ?E prima data cand intru in asa ceva sa repar asa ca orice sfat e bun.

update am schimbat bateriile la multimetru ...ca atunci cand am facut masuratorile cu pricina erau aproape duse. la bornele statie imi arata 8 ~ 8.2, iar la bornele boxelor 7.8~8 ohmi.se poate sa fi facut multimetrul figuri din cauza ca nu mai avea baterii? ca eu masuram atunci 5 sec se oprea...porneam iar masuram iar pe fuga..etc.
