Mbiri ya chitukuko cha luso phokoso akhoza kugawidwa mu magawo anayi: chubu, transistor, Integrated dera ndi field effect transistor.

Mu 1906, American de Forrest adapanga vacuum transistor, yomwe idachita upangiri waukadaulo wama electro-acoustic. Bell Labs inakhazikitsidwa mu 1927. Pambuyo pa teknoloji yolakwika ya ndemanga, chitukuko cha teknoloji ya audio chalowa m'nthawi yatsopano, monga Williamson amplifier wagwiritsa ntchito bwino teknoloji yosokoneza maganizo kuti achepetse kwambiri kusokonezeka kwa amplifier kwa zaka za m'ma 1950, chitukuko cha amplifier chubu chinafika nthawi yosangalatsa kwambiri, mitundu yosiyanasiyana ya amplifier opanda machubu amatuluka kumapeto. Chifukwa mtundu wa mawu a chubu amplifier ndi wotsekemera komanso wozungulira, amakondedwabe ndi okonda.

M'zaka za m'ma 1960, kutuluka kwa ma transistors kudapangitsa kuti anthu ambiri okonda ma audio alowe m'dziko lokulirapo. Ma transistor amplifiers ali ndi mawonekedwe a timbre osalimba komanso osuntha, kupotoza pang'ono, kuyankha pafupipafupi komanso kusiyanasiyana kosinthika.

Kumayambiriro kwa zaka za m'ma 1960, dziko la United States linayambitsa maulendo ophatikizana, omwe ndi mamembala atsopano aukadaulo wamawu. Kumayambiriro kwa zaka za m'ma 1970, maulendo ophatikizika adadziwika pang'onopang'ono ndi makampani opanga phokoso chifukwa cha khalidwe lawo lapamwamba, mtengo wotsika, voliyumu yaying'ono, ntchito zambiri ndi zina zotero. Mpaka pano, mabwalo ophatikizika amakanema amakanema ndi mabwalo ophatikizika a amplifier akhala akugwiritsidwa ntchito kwambiri pamayendedwe amawu.

Chapakati pa zaka za m'ma 1970, Japan idapanga chubu choyamba cholimbikitsa ntchito. Chifukwa chubu chamagetsi chamagetsi chimakhala ndi mawonekedwe amtundu wa ma elekitironi, mtundu wokhuthala komanso wotsekemera, komanso mitundu yosinthika ya 90 dB, THD <0.01% (100KHZ), posakhalitsa idakhala yotchuka pamawu. M'ma amplifiers ambiri masiku ano, ma transistors am'munda amagwiritsidwa ntchito ngati chomaliza.
