Si am observat ca sunetul este rece, nicidecum cald, iar partea de frecvente joase imi lipseste, insa frecventele inalte sunt redate destul de bine, predomina pot zice, amplificatorul este:

Este defazata un pic si face stanga dreapta, insa mentionez ca am folosit ca generator o aplicatie pentru generarea semnalului.

 

Traful de iesire este nou nout, fiind un traf de Darclee 2 ce avea ca tub final EL84.

Am respectat cu strictete valorile din schema, insa nu stiu ce sa zic.
