Nqus Tube lub mloog pob ntseg Amplifier - tus npau suav ntawm txhua txhua music lover

Yuav luag txhua suab ntaus ntawv yog nruab nrog ib tug connector rau headphones. Tej zaum qhov zoo tshaj ntawm lub teeb liab tau los ntawm no zes yog heev siab heev. Feem ntau nws yog los ntawm tej intermediate theem Circuit Court ntawm lub hwj chim amplifier, ces tus distortion nws muaj tsawg tshaj li tus kawg tso zis rau lub hais lus. Cuaj kaum, tus feem ntau rhiab suab zoo suab paj nruag lovers xum siv ib tug tshwj xeeb ntaus ntawv - lub tshuab nqus tsev raj lub mloog pob ntseg amplifiers.

Cov pub leejtwg mus rau lub chaw ntawm cov hluav taws xob tivthaiv, seemingly ntev outdated? Tom qab lub teeb muaj ib tug kuj loj geometric qhov ntev, nws yuav tsum tau ntxiv voltage qhov chaw pub rau filament nws thiaj li poob qhov teeb meem thiab routinely yuav tsum tau hloov, thiab tus nqi ntawm nws nta txiav txim siab. Tsis tas li ntawd rhuab, cov txheej txheem no ntau npaum li cas tshaj ib tug semiconductor. Yog, thiab koj yuav tsum tos tom qab tig, albeit luv luv-lived, thaum muaj ib tug "huab ntawm electrons" hauv daim iav teeb, thiab cov ib txwm nti - lub sij hawm thiab khwv tau!

Ntawm daim card yog yooj yim - cov nplua nuj thiab tus hluas lub suab, uas yog txawv raj lub mloog pob ntseg amplifier. Nws yog vim vim li cas ntawm lub cev thiab hluav taws xob xwm. High voltage ntawm lub anode thiab cathode sij ntau dynamic ntau yam, tsis muaj "kawg khoov rau ob sab" xam qhovkev nyob rau hauv semiconductor technology, thiab cov nce nyiaj pab ntau tshaj straightness daim duab nyob rau hauv cov ua hauj lwm ntau yam.

Tom qab amplification, lub teeb liab yog muaj raws li qhov kawg ntaus ntawv - ib tug loudspeaker, lub transformer yog teem rau no tso zis, tab sis nws zoo tseem unchanged thiab me ntsis distorted. Tube lub mloog pob ntseg amplifier muab lub siab tshaj plaws zoo suab tu tub tu kiv ob tsis muaj zog thiab mob siab heev tsawg zaus oscillations. Qhov no yog tshwj xeeb tshaj yog ib qho tseem ceeb thaum mloog symphonic music, uas yog tej zaum kuj heev nyob ntsiag to tog cov cuab yeej yog hloov los ntawm haib chords ntawm tag nrho cov orchestra.

Txhua leej txhua tus, txawm tus novice amateur xov tooj cua, tej zaum kuj yog ib lub teeb meem: yuav ib co coveted ntaus ntawv los yog ua rau nws tus kheej. Ntawm cov hoob kawm, tus tswv craftsmen tau me me, tab sis tsis muaj kev tsim txom nyob rau hauv sim, yog li ntawd koj yuav tau sim kom sau ib tug raj lub mloog pob ntseg amplifier nrog koj ob txhais tes.

Nws yog zoo dua mus pib nrog ib qho yooj yim schemes raws li nyob rau hauv ob chav triode 6N23P 6N6P. Lawv yog cov zoo nyob rau hauv uas txhua tus ntawm cov teeb yuav muab amplification ntawm ob raws, uas yog lub tso suab lub suab.

Nyob rau hauv thiaj li tsis mus thab ntau heev, rau lub caij pib nws yog qhov zoo tshaj plaws los ua kom sau ib leeg-lug ob-theem tshuab nqus tsev raj lub mloog pob ntseg amplifier nrog ib tug ntxiv nce transistor rau pem hauv ntej conduction. Nws ua rau nws tsis yooj yim, yooj yim kom raug position lub qhov chaw, tsis txhob crosstalk, uas yuav ua tau kom cov tom qab thiab zoo lub tswv yim.

Yuav kom zoo qhib tus sau "nyob rau hauv lub rooj" tswvyim yuav xav tau ib tug suab zaus generator thiab oscilloscope. Yog hais tias txhua yam yog nyob rau hauv kev txiav txim, koj muaj peev xwm npaj mus rau zus tau tej cov ntawv luam Circuit Court board , los yog ua tsis tau nws, raws li nws twb xyaum nyob rau hauv thaum ntxov hluav taws xob.

Nqus Tube lub mloog pob ntseg Amplifier nta yog suav tias yog ib tug neeg tseem ceeb cov khoom, yog li ntawd koj yuav tsum xav txog lwm tus tsim. Sami "teeb" tsis tau mus nkaum hauv lub cev, lawv yuav thov lawv amber teeb. Lub transformer yog feem ntau heev loj, yog li nws, dhau lawm, yuav kav tawm.
