Ntawm cov khoom siv hluav taws xob analog, amplifiers yog cov feem ntau. Nyob rau hauv lub neej txhua hnub, feem ntau koj yuav tsum tau kam nrog amplifiers ntawm audio (tsawg) zaus. Hauv ntej, lawv tau hu ua UZCH lossis ULF.
Xaiv lub tswvyim
Yog tias koj yeej tsis tau mus sib sau ua ke ib qho txuas ntxiv ntawm koj tus kheej, ces nws yog qhov zoo tshaj los pib ntawm kev sib txuas ntawm cov xov tooj cua ntawm cov xov tooj cua. Ib leeg mob stroke tube ultrasonic zaus hloov pauv tau yooj yim rau kev teeb tsa. Nws lub hwj chim txaus rau kev tso tawm suab hauv chav nyob, nws tuaj yeem siv ua suab nrov rau lub tshuab hluav taws xob lossis txuas nrog lub khoos phis tawm ua tus hais lus. Yog tias cov teeb ci nrog qhov siab ntxiv ntawm cov yam ntxwv tau siv rau hauv tus qauv, tom qab ntawd qhov kev cuam tshuam ntawm cov raj ib leeg yuav ua tau txaus rau kev sib txuas ncaj qha rau cov zis ntawm lub computer suab daim npav. Lub suab nrov siv lub zog tsim tawm kom phim cov neeg hais lus.
Cov ntsiab lus
Hauv qhov tso tawm suab no, koj tuaj yeem siv xov tooj cua octal 6P9 lossis nws cov ntiv tes sib piv - 6P15P. Cov teeb no muaj nyob hauv cov xovtooj qub thiab tseem tuaj yeem xaj yuav hauv khw xov tooj cua.
Lub hloov pauv Tr no haum rau TVZ-1-9 hom, tab sis koj tuaj yeem siv ib qho kev tso tawm ib leeg los ntawm lub raj TV lossis xov tooj cua. Nws yuav zoo heev yog tias koj tuaj yeem tau tuav ntawm qhov hloov pauv nrog tus hais lus tau siv nrog nws. Koj tuaj yeem khaws tus hais lus nrog lub zog tsawg kawg 2W, tiv thaiv ntawm 3 txog 8 Ohm. Koj tuaj yeem siv ntau tus neeg hais lus txuas hauv thaum uas tig mus lossis hauv cov kab ke.
Capacitor C2 yog lub ntsuas hluav taws xob, nws lub cev tau txuas nrog lub tshuab ua kom suab nrov. Capacitor C1 - txhua lub capacitor tsim rau qhov ntsuas hluav taws xob tsawg kawg yog 350 V.
Cov kuj tsis paub meej resistor R1 tseem coj los ntawm lub raj TV, nws yog qhov ntim tswj. Resistor R2 yog ntawm MLT-2 hom, tab sis lwm tus, tsim rau lub zog ntawm tsawg kawg 1.5W, tuaj yeem siv tau.
Lub zog hluav taws xob tuaj yeem siv tau npaj txhij-piv txwv, los ntawm lub teeb hluav taws xob mloog xov tooj cua. Qhov loj tshaj plaws yog tias nws muab qhov hluav taws xob tas li ntawm 210-250V los ua hluav taws xob hluav taws xob anode Circuit, thiab qhov hloov pauv ntawm 6, 3V rau cua sov lub raj xa hluav taws xob. Hauv ib qho ntawm cov qauv tsim ntawm cov qauv siv no, cov khoom siv fais fab ntawm cov neeg ua haujlwm Yunost hluav taws xob tau ua tiav tau yam tsis muaj kev hloov kho.
Kev tsim kho thiab teeb tsa
Lub tshuab ua kom nrov dua tau txuas rau U-zoo li tus hlau chassis, uas tuaj yeem siv los ntawm kev npog los ntawm qhov kawg ntawm lub neej CD tsav. Kuj tsis paub meej resistor thiab input txuas nyob rau hauv lub chassis tais. Yog hais tias lub suab nrov nrog cov hais lus thiab lub zog muab hluav taws xob tau tsim nyob rau hauv daim ntawv ntawm monoblock, tom qab ntawd nco ntsoov ua kom paub tseeb tias cov kev taw qhia ntawm lub tshuab hluav taws xob hloov pauv yog qhov sib txuam.
Kev teeb tsa txhua tus yog hinged. Tso lub teeb rau hauv vaj huam sib luag tsuas yog tom qab ua tiav kev teeb tsa thiab soldering, qhov no yuav tiv thaiv nws ntawm kev puas tsuaj. Cov neeg hais lus yog mounted cais ntawm cov txiab acoustic ua ntawm 5mm plywood. Tag nrho cov qauv muab tso rau hauv rooj plaub plywood them nrog leatherette. Koj tuaj yeem tso tus neeg hais lus tso rau hauv ib lub npov hais lus txawv. Koj tseem tuaj yeem tso lub hwj huam hluav taws xob cais thiab txuas rau ob lub suab sib xws, ua kom muaj lub tso suab.
Kho kom haum
Yog tias muaj lub suab nrov nrov tau hnov los ntawm cov lus thaum koj tig rau lub suab nrov, hloov lub suab nkag ntawm lub tshuab pauv Tr. Nrog rau kev teeb tsa kom zoo thiab chaw tau txais kev pabcuam, lub suab los ntawm tus hais lus yuav tsum muaj qhov pom tseeb, tsis muaj qhov pom tshwm tom qab. Qhov no ua tiav qhov teeb tsa ntawm lub zog loj. Thaum siv lub tshuab ua kom nrov dua li qhov txuas guitar, txuas nws dhau ntawm preamp lossis teebmeem pedal.
