Restaurare radio AIDA


Guest

Recommended Posts

In urma cu doua zile am primit prin posta un radio AIDA insa a ajuns foarte distrus.

Mi-am propus sa-l restaurez si sa incerc sa rezolv toate problemele aparute.

Deci o scurta evaluare a distrugerilor in exterior :

Pe unde medii si scurte se aude un pic cam incet...

Trebuie aliniata FI (evident se vad dereglate trafurile FI) dar si tubul EBF89 are cam 70% emisie catodica...

ECH81 e ok

ECL82 e ok.

condensatorul variabil a fost curatat si reglat pentru eliminarea scurtcircuitelor intre placi, am observat cu ocazia asta ca placa este fisurata sub CV (nu s-a intrerupt circuitul impimat )
