  4. Un amplificator se poate construi usor si simplu in micul nostru atelier Aceasta este schema http://i52.tinypic.com/29bjywk.gif Pasii de constructie , mentionez ca cutia am facuto la un prieten http://s1234.photobucket.com/user/mariagaby5/media/IMG_20150105_180422_zpsd97400e2.jpg.html http://s1234.photobucket.com/user/mariagaby5/media/IMG_20150106_110922_zps980cc739.jpg.html http://s1234.photobucket.com/user/mariagaby5/media/IMG_20150108_105248_zps68262368.jpg.html http://s1234.photobucket.com/user/mariagaby5/media/IMG_20150108_113555_zps7fcb75dc.jpg.html Si asa arata amplificatorul aproape finalizat http://s1234.photobucket.com/user/mariagaby5/media/IMG_20150108_133605_zpsf3b2d830.jpg.html http://s1234.photobucket.com/user/mariagaby5/media/IMG_20150108_133641_zps2bfc98b9.jpg.html Pentru transformatoarele de iesire am folosit transformatoare de cadre de la televizoarele pe lampi , am dat secundarul jos si am bobinat cu sirma de cupru de 0,5mm 75 de spire pentru 4 ohmi. Mentionez ca nu scoate 5w dar 2,5-3W este destul pentru o auditie intr-o camera Stima
