Tube kapena transistor amplifier?

Mpikisano pakati pa matekinoloje awiriwa wakhala ukupitirirabe. Zakale zimakhala ndi mbiri yochuluka ya zaka zoposa 100, zomalizirazo ndi pambuyo pake. Matekinoloje onsewa adapangidwa kuti apatse gitala mphamvu yoyenera. Komabe, mfundo yogwiritsira ntchito matekinoloje awiriwa ndi yosiyana kwambiri ndipo izi ndi zomwe zimapangitsa kuti amplifiers awa akhale osiyana komanso osiyana kwambiri. Zoonadi, ndizosatheka kunena kuti ndi luso liti lomwe lili bwino komanso mtundu wanji wa amplifier wabwinoko, chifukwa zimatengera zomwe woyimba gitala aliyense amakonda. Oyimba magitala ena sangathe kuganiza kuti akugwira ntchito pa amplifier ina iliyonse kuposa chubu, koma pali oimba ambiri omwe amagwira ntchito pa amplifiers potengera ma transistors kapena zotumphukira zamabwalo amakono ophatikizika. Ndithudi, luso lililonse lili ndi mphamvu ndi zofooka zake. 

Kusiyana kwa ntchito ya amplifiers payekha

Machubu amplifiers amapatsa gitala lathu phokoso lapadera kwambiri. Izi makamaka chifukwa cha mapangidwe awo, omwe amachokera pa nyali. Phokoso lochokera ku amplifier yotere limakhala lodzaza kwambiri, nthawi zambiri limakhala lamphamvu komanso, koposa zonse, kutentha. Machubu amplifiers amapangitsa mawu athu kukhala odziwika bwino ndikutitengera kudziko lina lamatsenga. Komabe, osati kuti zinali zabwino kwambiri, kupatula izi zabwino, amplifiers a chubu amakhalanso ndi zolakwika zambiri. Choyamba, ndi zida zomwe zimasowa mphamvu kwambiri ndipo zimatha kugwiritsa ntchito mphamvu zambiri kuwirikiza kangapo kuposa ma transistor amplifiers. Chifukwa chake panthawi yomwe kugogomezera kwambiri za chilengedwe ndi kupulumutsa mphamvu, ndiukadaulo wotsutsana. Komanso, miyeso yawo ndi kulemera kwawo sizosavuta kugwiritsa ntchito. Nthawi zambiri amatenga malo ochulukirapo ndipo amakhala olemera kwambiri kuposa omwe amatengera ma transistors kapena mabwalo amakono ophatikizika. Machubu amplifiers nawonso amakonda kuwonongeka kwamitundu yonse, kotero amafunikira chisamaliro chochulukirapo powagwira. Zikawonongeka, kukonza kumakhala kokwera mtengo kwambiri, ndipo muyenera kuganizira kuti nyali zimatha ndipo zimafunikira kusinthidwa nthawi ndi nthawi. Ndipo kusiyana kwina kofunikira kwambiri kuchokera ku transistor amplifier ndikuti amafunikira nthawi yochulukirapo kuti akonzekere kugwira ntchito. Mfundo ndi yakuti machubu athu ayenera kutentha bwino, ngakhale kuti ndi masekondi ochepa chabe a zochita, zomwe kwa magitala ambiri ndi mtundu wa mwambo komanso mwayi. Chomaliza, chofooka kwambiri cha machubu amplifiers ndi mtengo wawo. Nthawi zambiri imakhala yayikulu kwambiri kuposa ma transistor amplifiers okhala ndi mphamvu yofananira. Komabe, ngakhale ambiri akuwoneka opanda ungwiro, machubu amplifiers ali ndi otsatira awo omwe amafa. Chimodzi mwazosangalatsa za full-tube amplifiers ndi Blackstar HT-20R. Ili ndi, pakati pa ma tchanelo awiri, njira zinayi zomveka ndipo, monga momwe zimakhalira ndi amplifier yamakono, ili ndi purosesa ya digito. Blackstar HT-20R - YouTube

  Transistor amplifier ndiyotsika mtengo kwambiri, pogula ndikugwiritsa ntchito, ukadaulo womwe wakhala ukusintha nthawi zonse ndipo wasinthidwa kukhala mabwalo ophatikizika m'zaka zotsatira. Ndizopanga zambiri zochokera kuzinthu zotsika mtengo. Kugwiritsa ntchito mphamvu m'ma amplifiers oterowo kumakhala kotsika kangapo kusiyana ndi chubu amplifier, ndi nkhokwe yayikulu yamphamvu kwambiri nthawi imodzi. Chifukwa chake, ma transistor amplifiers ndi ang'onoang'ono, opepuka, otsika mtengo kugwiritsa ntchito ndi ntchito, ndipo nthawi zambiri amapereka ntchito zowonjezera. Mwachidule, iwo sakhala ovuta, komanso otsika mtengo kwambiri. Komabe, izi sizisintha mfundo yakuti ngakhale zonsezi, sizidzawonetsa bwino mlengalenga umene chubu amplifier ingapereke.

M'zaka zaposachedwapa, opanga, pofuna kukwaniritsa ziyembekezo za gitala wovuta kwambiri, nthawi zambiri amaphatikiza matekinoloje onse, kutenga zomwe zinali zabwino mu chubu chikhalidwe ndi transistor wamakono. Ma amplifiers oterowo amatchedwa ma hybrid amplifiers, chifukwa mapangidwe awo amatengera machubu onse ndi mabwalo amakono ophatikizika. Tsoka ilo, mtengo wokwera kwambiri ukhoza kukhala vuto lalikulu kwa oimba magitala ambiri.

Zotsatira zomaliza za phokoso lomwe timapeza kuchokera ku gitala lathu zimadalira kusankha kwa amplifier. Choncho, kusankha kwa chipangizochi chiyenera kukhala chofunikira komanso cholingalira monga kusankha gitala palokha. Kwa anthu omwe akufunafuna mtundu wina wa chiyambi ndi kutentha kwachilengedwe, chubu amplifier ikuwoneka ngati lingaliro labwino. Kwa onse omwe akufuna zida zopanda mavuto, zopanda mavuto pamtengo wotsika mtengo, amplifier ya transistor idzakhala yoyenera. Kumbali ina, kwa oimba gitala ovuta kwambiri, omwe ndalama zokwana zikwi zingapo sizidzakhala vuto, amplifier wosakanizidwa akhoza kukhala zomwe akufuna.
