Iyo nhoroondo yekuvandudza yeinzwi tekinoroji inogona kukamurwa kuita nhanho ina: chubhu, transistor, yakabatanidzwa dunhu uye munda mhedzisiro transistor.

Muna 1906, American de Forrest yakagadzira vacuum transistor, iyo yakapayona tekinoroji yemunhu electro-acoustic. Bell Labs yakavambwa muna 1927. Mushure meiyo yakaipa mhinduro tekinoroji, kuvandudza tekinoroji yeaudio yapinda munguva itsva, senge Williamson amplifier yakabudirira kushandisa iyo yakaipa mhinduro tekinoroji kuderedza zvakanyanya kukanganiswa kweiyo amplifier kusvika ku1950s, kukwidziridzwa kwechubhu amplifier kwakasvika imwe yenguva dzinonakidza, dzakasiyana-siyana dzechubhu amplifiers dzinobuda mumagumo ekupedzisira. Nekuti iyo ruzha ruvara rwechubhu amplifier inotapira uye yakatenderera, ichiri kufarirwa nevanofarira.

Muma1960, kubuda kwema transistors kwakaita kuti huwandu hukuru hwevanofarira odhiyo vapinde munyika yakafararira yeaudio. Transistor amplifiers ane hunhu hwehutete uye hunofamba timbre, yakaderera kukanganisa, yakakura frequency mhinduro uye ine simba renji.

Mukutanga kwema1960, United States yakatanga kuunza maseketi akasanganiswa, ari nhengo itsva dzetekinoroji yekuteerera. Mukutanga kwema1970, matunhu akabatanidzwa akazivikanwa zvishoma nezvishoma neindasitiri yekurira nekuda kwehupamhi hwepamusoro, mutengo wakaderera, vhoriyamu shoma, mabasa mazhinji uye zvichingodaro. Kusvika parizvino, gobvu firimu redhiyo rakasanganiswa maseketi uye anoshanda amplifier akasanganiswa maseketi ave achishandiswa zvakanyanya mumaseketi ekuteerera.

Pakati pe-1970s, Japan yakagadzira yekutanga basa rekuita basa rekurudzira chubhu. Nekuti iyo munda inobata simba chubhu ine hunhu hweerekitironi chubhu yakachena, gobvu uye inotapira toni ruvara, uye ine simba renji ye90 dB, THD <0.01% (100KHZ), yakakurumidza kuve yakakurumbira mukuteerera. Mune akawanda amplifiers nhasi, munda maitiro transistors anoshandiswa seyekupedzisira kuburitsa.
