Haeba u batla mokhoa o phethahetseng oa ho ntlafatsa lisebelisoa tsa hau tsa elektroniki u kanna oa batla ho nahana katube e le 'ngoe ea ho hanyetsa.Tsena li sebelisoa hangata litekong tsa potoloho le moralo.Li ka sebelisoa bakeng sa lits'ebetso tse ngata tse fapaneng tse kang, matla, hona joale, voltage, resistance, leakage ea hona joale le tse ling.Ha u batla li-tubes tsena u hloka ho etsa bonnete ba hore u fumana e nepahetseng bakeng sa kopo ea hau.Ho na le mefuta e mengata e fapaneng, ho kenyelletsa;bipolar, pentode, triode joalo-joalo.
Lebaka leo ka lona "bipolar tube" e ratoang haholo ke hobane e bonolo ho e kenya le ho e sebelisa ho lisebelisoa tsa elektronike.Sena ke hobane ha ba hloke mofuta ofe kapa ofe oa li-conductor kapa lisebelisoa ho phethela potoloho.Ho e-na le hoo, ke li-conductor tse bonolo feela tse hulang le ho fetola matla hore e be litekanyo tsa tsona tsa motlakase.Kahoo leha o sena boiphihlelo bo bongata ka lisebelisoa tsa elektroniki kapa o sa tsebe seo o se etsang, ho bonolo ho theha sena.U kopanya li-terminals tsa ho kenya ho liphetho tsa tsona tse tsamaellanang.
Haeba u batla ho fetolela tekanyo e phahameng ea matla hore e be litekanyo tse nyane, joale tube ea pentode e tla u fa khetho e ntle ka ho fetisisa.Ke e 'ngoe ea li-tubes tse tloaelehileng haholo bakeng sa litekanyetso tse phahameng tsa matla hobane li tla ka mefuta e mengata e fapaneng ea boholo bo fapaneng.Molemo o moholo oa li-tubes tsena ke hore li sebetsa hantle haholo ho fetola motlakase hore e be matla a mochini.Ha li hloke mofuta ofe kapa ofe oa likhoele kapa lisebelisoa tse ling mme sena se etsa hore ho be bonolo haholo ho li kenya.E ka boela ea kenngoa ho tloha holimo holimo e leng khetho haeba u sa tsotelle ho phunya masoba.
Lebaka le leng le etsang hore li-tubes tsa pentode li sebelisoe hangata hotube e le 'ngoe ea ho hanyetsas ke hobane li potlakile haholo ebile li nepahetse.Ba khona ho etsa hore mosebetsi o etsoe kapele ho feta mofuta ofe kapa ofe o tloaelehileng oa tube.Ba boetse ba khona ho sebetsa ka mokhoa o pholileng haholo hobane karolo ea bona ea ho pholisa fan e fumaneha botlaaseng ba sesebelisoa ka boeona se pholisang likarolo hantle haholo.Molemo o mong ho li-tubes tsena ke hore hangata li na le li-spikes tse nyane tse sothang, ho bolelang hore li utloahala li le ntle le hoja boemo ba lets'oao bo se holimo kamoo bo ka bang ka teng.
Haeba u batla ho sebelisa tube ho amplifier kapa lisebelisoa tse ling tsa elektronike tse matla haholo, ho bohlokoa hore u tsebe hantle hore na u sebetsana le eng.Ho na le mefuta e mengata e fapaneng ea li-tubes tse kenyelletsang bipolar, pentode le switching.U lokela ho khetha e nepahetseng kamehla bakeng sa ts'ebeliso e reriloeng kahoo etsa bonnete ba hore u etsa lipatlisiso tsa hau.Ka tsela ena u ke ke ua tšoenyeha ka ho senya likarolo leha e le life ha u sebelisa mofuta o fosahetseng oa tube.
Ha u batla ho reka atube e le 'ngoe ea ho hanyetsabakeng sa morero oa hau, etsa bonnete ba hore u botsa morekisi hore na ke mofuta ofe oa tube o ka loketseng kopo.Ba tla khona ho u fa mohopolo o motle ho latela litlhoko tsa hau hammoho le ho latela seo ba bang ba se rekileng haufinyane.Sena se tla thusa ho etsa bonnete ba hore o fumana sehlahisoa se nepahetseng bakeng sa litlhoko tsa hau.Etsa bonnete ba hore u fumana lintlha tsohle tseo u li hlokang pele u reka e le hore u tle u tsebe ho etsa qeto e nepahetseng mabapi le theko.
