Nu cred ca au fost postate schemele aceste de amplificatoare, dar daca au fost, imi cer scuze si rog administratorul sa le stearga. Din pacate, nu am gasit valorile la prima schema.

Comentarii @DJLeco:

Schema care este atasata prima, este o schema din care am dezvoltat mai incolo, modulele mele, valorile difera, atit la unele rezistente cit si la tranzistori, cit si schema de principiu.

O puteti incerca asa cum este, suna foarte bine la +/- 60-65Vcc.

Cablajul al 2-lea este PRAF, greseli elementare
