Amateka yiterambere ryikoranabuhanga ryijwi arashobora kugabanywamo ibyiciro bine: tube, transistor, guhuza umuzenguruko hamwe ningaruka za transistor.

Mu 1906, Umunyamerika de Forrest yahimbye vacuum transistor, yatangije ikoranabuhanga rya electro-acoustic.Bell Labs yavumbuwe mu 1927. Nyuma y’ikoranabuhanga ribi ryo gutanga ibitekerezo, iterambere ry’ikoranabuhanga ry’amajwi ryinjiye mu bihe bishya, nka Williamson amplifier yakoresheje neza ikoranabuhanga ribi kugira ngo agabanye cyane kugoreka kwa amplifier kugeza muri 1950, iterambere rya amplifier ya tube yageze mugihe kimwe gishimishije cyane, imiyoboro itandukanye ya tube igaragara mugihe kitagira iherezo.Kuberako ibara ryamajwi ya tube amplifier iryoshye kandi irazengurutse, iracyakundwa nabakunzi.

Mu myaka ya za 1960, kugaragara kwa tristoriste byatumye umubare munini wabakunda amajwi binjira mwisi yagutse.Amashanyarazi ya Transistor afite ibiranga timbre yoroheje kandi yimuka, kugoreka gake, kwaguka kwinshi kwinshi hamwe ningaruka zingana.

Mu ntangiriro ya za 1960, Amerika yatangije bwa mbere imiyoboro ihuriweho, ikaba ari abanyamuryango bashya b'ikoranabuhanga ry'amajwi.Mu ntangiriro ya za 70, imiyoboro ihuriweho yamenyekanye buhoro buhoro ninganda zijwi kubera ubuziranenge bwazo, igiciro gito, ingano nto, imirimo myinshi nibindi.Kugeza ubu, firime yuzuye amajwi yahujwe hamwe na amplifier ikora ikoreshwa cyane mumashanyarazi.

Mu myaka ya za 70 rwagati, Ubuyapani bwakoze umusaruro wambere wo gukora akazi.Kuberako imbaraga zingufu zumurima zifite ibiranga umuyoboro wa elegitoroniki yera, ibara ryijimye kandi ryiza, hamwe nimbaraga zingana na 90 dB, THD <0.01% (100KHZ), bidatinze byamenyekanye mumajwi.Muri amplifier nyinshi uyumunsi, transistors yumurima ikoreshwa nkibisohoka byanyuma.
