Ishubhu noma i-transistor amplifier?

Umncintiswano phakathi kobuchwepheshe obubili ubulokhu uqhubeka. Owokuqala unomlando ocebile weminyaka engaphezu kwe-100, owakamuva kamuva kakhulu. Bobabili ubuchwepheshe bakhelwe ukunikeza isiginci amandla afanele. Kodwa-ke, isimiso sokusebenza kwalezi zobuchwepheshe ezimbili sihluke ngokuphelele futhi yilokhu okwenza lezi zikhulisi zihluke kakhulu futhi zihluke kakhulu komunye nomunye. Ngokuqinisekile, akunakwenzeka ukusho ukuthi iyiphi ubuchwepheshe obungcono nokuthi yiluphi uhlobo lwe-amplifier olungcono, ngoba kuncike kakhulu ekuthandweni komuntu ngamunye kwesiginci ngasinye. Abanye abashaya isiginci abakwazi ukucabanga ukuthi basebenza kunoma iyiphi enye i-amplifier kuneshubhu eyodwa, kodwa baningi abashaya isiginci abasebenza kuphela kuma-amplifiers asekelwe kuma-transistors noma okuphuma kokunye kwamasekethe ahlanganisiwe esimanje. Impela, ubuchwepheshe obunye bunamandla nobuthakathaka babo. 

Umehluko ekusebenzeni kwama-amplifiers ngamanye

Ama-Tube amplifiers anikeza isiginci sethu umsindo ohluke kakhulu. Lokhu ikakhulukazi ngenxa yokuklama kwabo, okusekelwe ezibani. Umsindo ovela ku-amplifier enjalo ngokuqinisekile ugcwele kakhulu, ngokuvamile unamandla futhi, ngaphezu kwakho konke, ukufudumala. Ama-Tube amplifiers anika umsindo wethu isimo esiyingqayizivele futhi asiyise ezweni elithile lomculo omlingo. Kodwa-ke, hhayi ukuthi bekukuhle kakhulu, ngaphandle kwalezi zici ezinhle, ama-tube amplifiers nawo anokungapheleli okuningi. Okokuqala, angamathuluzi alambele kakhulu amandla futhi angasebenzisa amandla aphindwe izikhathi eziningana kunama-transistor amplifiers. Ngakho-ke ngesikhathi lapho kugcizelelwa kakhulu emvelweni nokonga amandla, kuwubuchwepheshe obuyimpikiswano. Futhi, ubukhulu nesisindo sazo akusebenziseki kakhulu. Ngokuvamile zithatha isikhala esiningi futhi ngokuqinisekile ziyizikhulisamandla ezisindayo kunalezo ezisekelwe kuma-transistors noma amasekethe ahlanganisiwe esimanje. Ama-Tube amplifiers nawo athambekele kakhulu kuzo zonke izinhlobo zokulimala kwemishini, ngakho adinga ukunakekelwa okwengeziwe lapho ewaphatha. Uma kwenzeka umonakalo, ukulungisa kubiza kakhulu, futhi kufanele ucabangele ukuthi izibani ziyaguga futhi zidinga ukushintshwa ngezikhathi ezithile. Futhi omunye umehluko obaluleke kakhulu ovela ku-transistor amplifier ukuthi badinga isikhathi esengeziwe ukuze balungele ukusebenza. Iphuzu liwukuthi amashubhu ethu kufanele afudumale ngendlela efanele, nakuba kunjalo nje imizuzwana embalwa yesenzo, okuyinto kubadlali abaningi besiginci kuwuhlobo lwesiko kanye nenzuzo. Ubuthakathaka bokugcina, obukhulu kakhulu be-tube amplifiers yintengo yabo. Ivamise ukuba nkulu kakhulu kunasesimeni sama-transistor amplifiers anamandla afanayo. Kodwa-ke, naphezu kokungapheleli okuningi kangaka, ama-tube amplifiers anabalandeli bawo abaqinile. Esinye sezikhulisi zeshubhu eligcwele elithakazelisa kakhulu iBlackstar HT-20R. Ine, phakathi kokunye iziteshi ezimbili, izinketho ezine zomsindo futhi, njengoba kufanele i-amplifier yesimanje, ifakwe iphrosesa yemiphumela yedijithali. I-Blackstar HT-20R – YouTube

  I-transistor amplifier ishibhile, kokubili mayelana nokuthenga nokusebenza, ubuchwepheshe obulokhu buguquka njalo futhi buguqulelwe kumasekhethi ahlanganisiwe eminyakeni elandelayo. Ukukhiqizwa ngobuningi okusekelwe ezintweni ezishibhile. Ukusetshenziswa kwamandla kuma-amplifiers anjalo kuphansi izikhathi eziningana kune-tube amplifier, ene-reserve enkulu yamandla aphezulu ngesikhathi esisodwa. Ngakho-ke, ama-amplifiers e-transistor mancane, alula, ashibhile ukusebenzisa kanye nesevisi, futhi ngokuvamile ahlinzeka ngemisebenzi eyengeziwe eyengeziwe. Kafushane, azinzima kangako, kodwa futhi ishibhile kakhulu. Kodwa-ke, lokhu akulishintshi iqiniso lokuthi naphezu kwazo zonke lezi zinsiza, ngeke zibonise ngokugcwele umkhathi onganikezwa yi-tube amplifier kuphela.

Eminyakeni yamuva, abakhiqizi, befuna ukuhlangabezana nokulindelwe kwabadlali besiginci abadinga kakhulu, bavame ukuhlanganisa kokubili ubuchwepheshe, bethatha okungcono kakhulu ku-tube yendabuko kanye ne-transistor yesimanje. Ama-amplifiers anjalo abizwa ngokuthi ama-amplifiers e-hybrid, ngoba ukwakhiwa kwawo kusekelwe kokubili amashubhu kanye neziyingi zesimanje ezihlanganisiwe. Ngeshwa, inani eliphezulu kakhulu lingase liphazamise kakhulu abadlali besiginci abaningi.

kufinyeta

Umphumela wokugcina womsindo esiwuthola kusiginci sethu uncike ekukhetheni kweamplifier. Ngakho-ke, ukukhetha kwalesi divayisi kufanele kube okubalulekile nokucabangela njengokukhethwa kwegitala ngokwayo. Kubantu abafuna uhlobo oluthile lokwangempela nokufudumala kwemvelo, i-tube amplifier ibonakala iyisiphakamiso esingcono. Kubo bonke abafuna imishini engenazinkinga, engenazinkinga ngentengo engabizi, i-transistor amplifier izoba efaneleka kakhulu. Ngakolunye uhlangothi, kubadlali beziginci abafuna kakhulu, lapho izindleko eziyizinkulungwane ezimbalwa ngeke zibe yinkinga, i-amplifier ye-hybrid ingaba yilokho abakufunayo.
