Problema hiss si ecranare amplituner

Recommended Posts

Se da un amplituner stereo sony (str-de135, finale pe tranzistoare). Am doua chestii care ma deranjeaza un pic la el:


- are hiss constant (nu e influentat de volum sau sursa), slab dar perceptibil din cauza ca boxele sint pe birou la jumate de metru de urechile mele


- sta chiar linga birou pe partea dreapta si prinde zgomot de la celular (cind e activitate pe radio) - nu prea am unde sa-l mut, poate cu 30cm mai departe de mine daca fac un pic de "defragmentare"


Carcasa e metalica; cablul de alimetare nu e ecranat dar posibil sa primeasca pamintare prin masa pe ruta pc -> dac


Se poate face ceva (barem la prima parte)?
