Amateka yiterambere yikoranabuhanga ryijwi arashobora kugabanywamo ibice bine: tube, umutego, umuzenguruko winjijwe hamwe nimyandikire.

Mu 1906, umuhango wo muri Amerika wahimbye wanduza vacuum, ubupayiniya bwa elegito-acoustic ikoranabuhanga. Inzogera yavumbuwe mu 1927. Nyuma y'ikoranabuhanga ribi, iterambere ry'ikoranabuhanga ryakoreshejwe mu myaka ya za 1950, iterambere rya Amplifiers rishimishije ku kugoreka byinshi, amplifiers yo mu tugero iragaragara mu gihe kitagira iherezo. Kuberako ibara ryumvikana rya amplifier ya amplefier iraryoshye kandi rizengurutse, iracyakundwa nabatezimbere.

Mu myaka ya za 1960, hagaragaye abaseruzi bakoze umubare munini w'amajwi avuga ko abakunzi ba mausi bandika isi yagutse. Ameristor amplifiers ifite ibiranga byoroshye kandi byimuka, kugoreka hasi, igisubizo kinini gisubiza inshuro nyinshi.

Mu ntangiriro ya za 1960, Amerika yashizeho bwa mbere imirongo ihuriweho, aribigizemo uruhare bashya mu ikoranabuhanga ryamajwi. Mu ntangiriro ya za 70, imirongo ihuriweho yagaragaye buhoro buhoro n'inganda zumvikana kubera ubuziranenge bwabo, igiciro gito, ingano nto, imikorere mito nibindi. Kugeza ubu, amajwi yinjira mu majwi yuzuyemo imirongo hamwe na amplifier ya Amplifier yinjijwemo yakoreshejwe cyane mu mpeshyi.

Mu myaka ya za 1970, japan yasohoye amateka yambere yakazi. Kuberako umurima ufite imbaraga umuyoboro ufite ibiranga umuyoboro wera wa electron, ibara ryijimye kandi ryiza, hamwe na 90 db, thd <0.01% (100khz Muri amplifiers nyinshi muri iki gihe, inyandiko zingirakamaro zikoreshwa nkibisohoka byanyuma.
