Iityhubhu ze-vacuum zizixhobo ezikhethekileyo ezinceda ekulawuleni umbane. Zazithandwa kakhulu ngaphambili, ingakumbi kwiirediyo nakwiiTV. Nokuba sisebenzisa ii-transistor kakhulu kule mihla, iityhubhu ze-vacuum zisabambe indawo ephambili kwezinye iindawo. Zinokunyusa isandi kwizixhobo zomculo kwaye zisebenza kwii-amplifier ezithile. Iinkampani ezifana ne-Esseniot zenza kube lula ukuzisebenzisa. isibhedlele senkqubo yetyhubhu iisetingi abantu kunye neenkampani abanokuzithemba. Kwaye ezi nkqubo azizozinto zakudala kuphela; zisasebenza kubuchwepheshe banamhlanje kwimisebenzi ethile.
Ngoko ke, ukufumana iinkqubo zeetyhubhu ze-vacuum ezifanelekileyo ngobuninzi kunokuba mnandi. I-Esseniot ifumene iityhubhu ezahlukeneyo zeemfuno ezahlukeneyo. Kungcono ukukhangela kwi-intanethi kuqala, kuba iiwebhusayithi zezixhobo ze-elektroniki zihlala zinezivumelwano. Unokufumana izinciphiso zokuthenga ngobuninzi. Oko kuthetha ukuba wonge imali ukuba uthenga izinto ezininzi ngaxeshanye. Imiboniso yorhwebo yenye indawo elungileyo. Apho udibana nabenzi, ubuze izinto ngokuthe ngqo, ubone iimveliso kufutshane kwaye uve. Iivenkile zasekuhlaleni ngamanye amaxesha zithengisa iityhubhu ngobuninzi, ngoko ke cela ukuthengiswa ngobuninzi xa undwendwela. Soloko uthelekisa amaxabiso. Funda uphononongo, kuba impendulo ibonisa umgangatho. Iinkampani ngamanye amaxesha zithengisa, hlala ubukele. Fowunela okanye uthumele i-imeyile kubathengisi ukuze ufumane izibonelelo ezingcono—basenokunciphisa amaxabiso ukuba babuza. Jonga iwaranti ngaphambi kokuba uthenge, ngoko ukuba kukho ingxaki, lungisa.
Xa ufuna iinkqubo zeetyhubhu ze-vacuum zeshishini, jonga izinto ezibalulekileyo. Okokuqala, cinga ngento oyifunayo. Ukusetyenziswa okwahlukeneyo kufuna iityhubhu ezahlukeneyo. Njengokuba, ezinye zingcono kwizixhobo zesandi, ezinye kwiirediyo. Umgangatho ubaluleke kakhulu. Ufuna iityhubhu zakhiwe kakuhle kwaye zihlala ixesha elide. Jonga ukuba umenzi ofana no-Esseniot ufumene igama elihle na, usindisa kwinkunkuma ephuka ngokukhawuleza. Okulandelayo, jonga iinkcukacha—amandla kunye nobukhulu kunceda ukukhetha okulungileyo. Ukuba awuqinisekanga, buza iingcali; ziyakukhokela. Ixabiso lilungile ukucinga nalo. Fumana umgangatho kodwa ungahlawuli kakhulu. Thelekisa ababoneleli ngezivumelwano. Kwaye inkxaso emva kokuthenga ibalulekile. Ezinye iinkampani zinika inkonzo entle ukuba kuvela iingxaki. Khetha enye encedayo ukusetyenziswa kwenkqubo yetyhubhu yepneumatic, ngoko ke i-biz isebenza kakuhle.
Iinkqubo zeetyhubhu zokucoca umoya ziyathandwa kakhulu kumashishini ngoku. Zazisetyenziswa koomatshini kuba zisebenza kakuhle. Esinye isizathu kukuba zilawula amandla amaninzi. Iifektri zifuna ukusebenza okuthe tye okukhuselekileyo, kwaye iityhubhu ziyanceda oko. Zilawula ukuhamba kombane kakuhle, zenza oomatshini basebenze kakuhle—amandla angasetyenziswayo angachithiyo, zonga imali kwaye zilungele umhlaba.
Kwakhona, ezi tyhubhu zihlala ixesha elide. Ngokungafaniyo nezinye iindawo, aziphuki lula. Esi sisitshixo sokuqina kweshishini esiqhuba oomatshini imihla ngemihla. Ukonakala kwezixhobo kubiza kakhulu ukulungisa. Ngoko ke, iityhubhu ziyakuthintela oko, ukukhetha okukrelekrele.
Ukongeza, iityhubhu zisebenza kwiindawo ezinzima. Njengokwemba okanye ioyile, apho uthuli lumanzi khona ngobushushu. Iindawo eziqhelekileyo ziyasilela apho, kodwa iityhubhu ziyayiphatha. inkqubo yetyhubhu yomoya Uyilo lweetyhubhu ezilungele iimfuno zoshishino. Ngobuchwepheshe bethu, iinkampani ziphucula imveliso kwaye oomatshini bahlala ixesha elide.
Abantu abaninzi abayiqondi kakuhle inkqubo yeetyhubhu ze-vacuum. Enye enkulu kukuba zindala kwaye zimbi kuneteknoloji entsha. Yinyani leyo. inkqubo yetyhubhu yesibhedlele zijikeleze ixesha elide, kodwa zisaluncedo nanamhlanje. Amashishini abona ukuba zintsha kwezinye iindawo, njengokuphatha umbane ophezulu ngcono.
