Ezincamathelayo Tube yoLungiso sesimangalo - iphupha yonke lover umculo

Phantse nasiphi na isixhobo emanyelwayo mayixhotyiswe isinxibelelanisi for headphones. Ngamanye amaxesha umgangatho umqondiso ezifunyenwe kule kwindlwane kakhulu phezulu. Kudla kuthathwe na ixesha yesekethe eliphakathi le wokukhulisa amandla, ngoko ukufiphala luqulethe ngaphantsi kwe imveliso yokugqibela izithethi. Noko ke, le olubuthathaka kakhulu ixilongo abathandi umculo kwizinga bakhetha ukusebenzisa isixhobo ezikhethekileyo - ongenawo yokukhulisa ityhubhu yoLungiso.

Imfihlo ukuthandwa licandelo lektronikhi, zibonakala elide kuphelelwa? Emva kokuba isibane uye imilinganiso elikhulu zejometri, oko kufuna umthombo wamandla ombane ezongezelelweyo bondle cingwana ekugqibeleni ulahlekelwa mba kwaye qho kufuneka itshintshwe, yaye ixabiso layo kule mihla kakhulu. Kwakhona shushu, le ndlela ungaphezulu kakhulu kokuba semiconductor. Ewe, kwaye kufuneka ukuba ulinde emva ekuguquleni, nangona siphila ixesha elifutshane, xa kukho "ilifu elektroni 'ngaphakathi ibhalbhu iglasi, kwaye chip njengesiqhelo - ixesha uzuze!

Le mfihlelo ke ilula - abazizityebi iindaba zimnandi isandi, nto leyo yahluke msindo tube yoLungiso. Oku kungenxa yezizathu endalo ngokwasemzimbeni kunye zombane. ombane aphezulu phakathi anode kunye cathode uchaza uluhlu olubanzi eliguqukayo, akukho "ukugoba ekupheleni 'ezendeleyo kwezobuchwephesha semiconductor, Nongeniselo ubuninzi tye ngumzobo kuluhlu esebenzayo.

Emva okhulisa, uphawu phathiso luyangqinelana isixhobo lokugqibela - lokuhlaba, nesiguquli umiselwe le mveliso, kodwa imilo yayo ihleli ingatshintshanga kwaye kancinane zonakaliswa. Tube yoLungiso sesimangalo inika umgangatho odiyo yokuzala ephezulu kokubini buthathaka kwaye olunzulu ephantsi-amaza oscillations. Oku kubaluleke ngakumbi xa ndiphulaphule umculo Symphonic, nto leyo maxa wambi izixhobo iqela cwaka kakhulu athathelwa indawo taxi enamandla yonke orchestra.

Wonke umntu, nditsho manqindi engahlawulwayo radio mfundi, maxa wambi kukho a byi: ukuthenga isixhobo abathile okanye wenze kube ngokwakho. Kakade ke, inkosi iingcibi eba encinane, kodwa akukho ngozi ekuzameni, ngoko unga zama ukuqokelela umbhobho yoLungiso msindo ngezandla zakho.

Kubhetele ukuba uqale kunye namacebo elula ngokusekelwe triode kabini 6N23P 6N6P. Ukuba ulungile ukuba sihlandlo ngasinye kwezi izibane nako ukunika yokukhulisa imiphantsi amabini, nto leyo isandi yesitiroyo.

Ukuze ungenakuwuxhalabela kakhulu kakhulu, kuba isiqalo kuhle ukuzama ukuqokelela inqanaba-ezimbini ezincamathelayo ityhubhu yoLungiso msindo olunye-baphela inzuzo transistor Uhanjiso ezongezelelweyo phambili. Oku kwenza kube nzima, kunzima ukubeka ngokuchanekileyo iindawo, uphambuke ezintethweni crosstalk, nto leyo ikhokelele ekubeni imvelaphi kunye nengxelo ngokuqhubekayo ethembisa kakhulu.

Ukuze ihambelane i eqokelelwe "phezu kwetafile" scheme kuya kufuneka umsindo sokuquqa generator kunye oscilloscope. Ukuba yonke into ingendlela, uyakwazi ukuqhubeka ukuya kwimveliso ibhodi yesekethe eprintiweyo , okanye wenze ngaphandle kwayo, njengoko lwalusenziwa ngamayelenqe ekuqaleni elektroniki.

Ezincamathelayo Tube yoLungiso sesimangalo mihla kugqalwa i izixhobo abakhethiweyo, ngoko umele ucinga ngayo kuyilo lwangaphandle. Sami "bulb" akuyomfuneko ukuba ukuzimela ngaphakathi emzimbeni, baya ukukholisa izibane zazo yegolide evuthiweyo. Nesiguquli idla kakhulu elikhulu, ngoko ke, nayo, bakholisa ukuba sinikele phandle.
