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 idapangidwa mu 1927. Pambuyo paukadaulo wamawu olakwika, chitukuko chaukadaulo wamawu chalowa m'nthawi yatsopano, monga Williamson amplifier adagwiritsa ntchito bwino ukadaulo wamayankho olakwika kuti achepetse kwambiri kupotoza kwa amplifier mpaka 1950s, chitukuko cha chubu amplifier inafika nthawi yosangalatsa kwambiri, machubu amplifier osiyanasiyana amatuluka mosalekeza.Chifukwa mtundu wamawu wa 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 a kanema ndi mabwalo ophatikizika a amplifier akhala akugwiritsidwa ntchito kwambiri pamayendedwe amawu.

M'katikati mwa zaka za m'ma 1970, Japan inapanga chubu choyamba chothandizira 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.
