Buna ziua!Am o schema a unui aparat rusesc de radio UM-UL, ceva in genul Iris-ului nostru, doar ca schema e mai complicata. Se vede pe schema o piesa cu 3 pini, care nu este tranzistor. Daca cineva ma poate lamuri ce este, multumesc anticipat. Ester prima data cand vad o astfel de piesa si un astfel de simbol intr-o schema de radio.Atasez si poza schemei si poza din interiorul radioului.

Va multumesc!Totusi sunt nelamurit.Piesa aia verde este un filtru piezo ceramic. Piesa cu 3 pini este cea alba, in carcasa de plastic. Din cate stiu, filtrele piezoceramice nu arata asa. Poate ma insel...
