Nhoroondo yekuvandudza tekinoroji yakanaka inogona kukamurwa kuita zvikamu zvina: Tube, transistor, yakabatanidzwa mudunhu uye transistor endarama.

Muna 1906, American de Forrest Yakagadzirwa Vacuum Transistor, iyo yakapayona electrology yemunhu-acoustic tekinoroji. Bell Labs yakagadzirwa muna 1927 Nekuti ruvara rwekunze rwe tube amplifier inotapira uye kutenderera, ichiri kusarudzwa nevaenzi.

Muna 1960s, kubuda kwevatengesi kwakaita kuti huwandu hwakawanda hweanoshingaira venzvimbo dzinoenda kune imwe nyika yekuteerera. Transistor Amplifiers ane hunhu hwekutema uye kufambisa nguva

Mukutanga kwa1960s, United States yakatanga kuunzwa masango, ayo ari nhengo nyowani dzekuteerera technology. Mukutanga kwa1970s, zvadzinobatanidzwa zvapera zvishoma nezvishoma nendasitiri inoshamisa kwazvo nekuda kwemhando yemhando yavo yakakwirira, mutengo wakaderera, mhuru diki, mabasa mazhinji uye zvichingodaro. Kusvika ikozvino, firimu rakakomberedza Audio rakabatanidzwa masenduru uye mashandiro aAmplifier akasanganiswa matunhu akashandiswa zvakanyanya mumatunhu ekuteerera.

Pakati ma1970s, Japan yakaburitsa yekutanga yemunda basa rekurudziro tube. Nekuti iyo munda inogadzirisa simba remagetsi emagetsi akachena Electron Tube Mune akawanda amplifiers nhasi, munda wekutsigira anoshandiswa seyekupedzisira kubuda.
