buna seara!am  ocazia sa  iau la un pret decent acest amplificator conservat excelent,inclusiv cu boxele sale originale.as dori  sa stiu daca se merita cumparat la pretul de 350  de lei avand in vedere ca  puterea este de numai 2 wati.alta  problema  ar fi  ca  boxele  au impedanta de  15 ohmi,deci  daca pun altele ar trebui sa gasesc  cu aceeeasi impedanta?

asta avr fi apmlificatorul http://tubeampli.blogspot.ro/

multumesc anticipat

E un amplificator comercial, bun pentru vremea lui, putin depasit azi si departe de high-end, dar la banii astia eu zic ca merita...se mai poate eventual imbunatati. As fi curios si eu de ceva poze, nu stiu cum arata boxele originale...nu stiam ca s-a vandut si cu boxe. Se pot pune in serie doua perechi de boxe asemanatoare pe 8 ohmi, numai sa ai grija sa fie bine facute legaturile si fazarea difuzoarelor. Nu uita ca un amplificator pe lampi se poate distruge daca nu are difuzoare pe iesire, chiar si scurt timp!

Si eu recomand schimbarea tuturor electroliticilor si verificarea condensatoarelor de cuplaj, dar macar asigura-te ca ai sigurante bune, nu litze puse de vreun mester. O fi el conservat bine exterior - poate chiar putin folosit, dar sunt componente care imbatranesc...
