1. Ọkà Okwu: iji guzogide mmetụta nke mkpali siri ike mberede na mgbaàmà mmemme na-enweghị mmebi ma ọ bụ mgbagọ. Nke a bụ uru ihe atụ iji zoo aka na ya: ike ọkwa aha nke onye ọkà okwu ahọpụtara kwesịrị ịdị okpukpu atọ karịa nke mgbakọ echiche.
2. Igwe olu ike: ma e jiri ya tụnyere igwe olu ike transistor, ebe nchekwa ike achọrọ dị iche. Nke a bụ n'ihi na usoro ibufe ibu nke igwe olu ike tube dị nro. Maka oke nke akara egwu juputara na oke ibu, igwe olu ike tube anaghị emepụta ihe na-akpata oke ibu, kama ọ na-eme ka nsọtụ elu ahụ bụrụ gburugburu. Nke a bụ ihe anyị na-akpọkarị elu nke ịkpụcha ihe na-agbanwe agbanwe. Mgbe igwe olu ike transistor gasịrị na ebe ibufe ibu, mgbagọ na-abụghị nke ahịrị na-abawanye ngwa ngwa, nke na-eme ka nnukwu mbelata ebili mmiri na mgbagọ ahụ. Ọ naghị eme oke gburugburu, kama ọ na-ehicha ya nke ọma. Ụfọdụ ndị na-eji mgbochi nke iguzogide, inductance na capacitance mee ka igwe okwu ahụ dị ka igwe okwu, ma nwalee ikike mmepụta nke ọtụtụ ụdị igwe olu ike transistor dị elu. Nsonaazụ ya na-egosi na mgbe ibu ahụ nwere mgbanwe nkebi, enwere igwe olu ike 100W, ike mmepụta n'ezie bụ naanị 5W mgbe mgbagọ ahụ bụ 1%! Ya mere, nhọrọ nke ego nchekwa nke igwe olu ike transistor:
Igwe okwu ntụkwasị obi dị elu: ugboro iri
Igwe okwu ike dị elu nke obodo: ugboro isii
Igwe okwu ike etiti obodo: ugboro atọ ugboro anọ
Igwe amplifier ike nke tube nwere ike ịdị obere karịa nke dị n'elu.
3. Ego ole ka a ga-ahapụ maka ọkwa nrụgide ụda nkezi na ọkwa nrụgide ụda kachasị elu nke sistemụ ahụ. Ọ kwesịrị ịdabere na ọdịnaya na gburugburu ebe ọrụ nke mmemme mgbasa ozi ahụ. 10dB a kacha nta a na-anaghị agbanye, maka egwu pop nke oge a, ịwụ elu bungee na egwu ndị ọzọ, ọ kwesịrị ịhapụ 20 ~ 25dB redundancy, ka sistemụ ọdịyo ahụ wee rụọ ọrụ nke ọma. Na-arụ ọrụ nke ọma ma na-aga n'ihu.
