inlocuire potentiometru - analog cu digital

Recommended Posts

Buna tuturor..Am si eu aici o schema http://radiosammlung.homepage.t-online.de/seite8.html ->e a doua,cea cu tranzistor FET in sursa caruia se afla un potentiometru de 25K.Am vazut in oras ca exista si potentiometre digitale, tot cu 3 pini si arata la fel ca unul analogic.Problema ar fi ca uneori fasaie potentiometru ala..Am avut unul bun, dar s-a defectat apoi ce am cumparat erau prost capsate si cand mergeau cand nu.S-ar putea inlocui acel potentiometru de 25K din circuitul sursei cu unul digital?

Va multumesc!
