Cov Lus Qhia
Kauj ruam 1
Ua ntej pib kho cov khoom siv kom nrov nrov, tshem nws tawm ntawm lub tsheb. Ua ntej tshaj lub ntsiab fuse rau lub hwj chim muab cable. Txuas txhua lub hwj chim, hais lus thiab teeb liab xov hlau. Yog tias cov xov hlau no yog tib xim thiab tib lub taub, nco ntsoov khij qhov ntxiv thiab rho tawm.
Kauj ruam 2
Siv daim ntaub ntub los so plua plav tawm ntawm cov tsev amplifier.
Kauj ruam 3
Disassemble lub suab nrov. Txhawm rau ua qhov no, tshem tawm cov npog hauv qab, dismantle lub pluaj mounting ntawm cov zis transistors thiab cov tuav hluav taws xob tuav, tshem tag nrho cov ntsia hlau txuas uas tuav lub rooj tsav xwm rau rooj plaub. Siv cov ntsia hlau me me, ua tib zoo cais cov tso zis tawm ntawm cov roj hmab-ntaub npuag, tom qab ntawd tshem lub rooj tsavxwm los ntawm rooj plaub.
Kauj ruam 4
Siv ib qho ohmmeter los nrhiav cov teeb meem tso zis teeb meem transistors. Yuav kom ua tau li no, lawv yuav tsum muaj suab av, tk. cov lus sib dhos hauv cov tshuab hluav taws xob feem ntau yog sib xyaw, thiab ib qho tshuab transistor ntu yuav luv luv-tag nrho cov hluav taws xob Circuit Court.
Kauj ruam 5
Saib ze ze ntawm cov ciav hlau thiab lwm yam ntawm cov tso suab ntu tsim tawm theem. Ib qho transistor tawg tuaj yeem ua rau qee qhov chaw puas. Siv ib qho ohmmeter, kuaj cov transistors ntawm theem ua ntej-theem thiab cov resistors txuas rau lawv, nrog rau cov ciav hlau ntawm cov ntawv luam tawm Circuit Court.
Kauj Ruam 6
Thaum lub tshuab hluav taws xob tso zis tsis muag rau hauv qhov chaw, ua qhov kev sim tig mus nrog 12V kuaj ntsuas lub zog kom paub tseeb tias qhov hloov hluav taws xob ua rau lub tshuab hluav taws xob ua haujlwm. Yog tias lub teeb ntsuab LED teeb hloov, qhov hloov hluav taws xob tau OK.
Kauj Ruam 7
Hloov qee qhov tsis zoo uas muaj qhov qub lossis zoo sib xws.
Kauj ruam 8
Tshawb xyuas qhov chaw ntawm kev faib ua ntu ntawm seem hloov. Soldering yuav tsum yog cov khoom zoo.
Kauj Ruam 9
Siv tus ntsuas kub, ntsuas qhov ntsuas kub ntawm qhov xwm txheej ntawm cov zis transistors thiab sau qhov tseem ceeb rau ntawm daim ntawv.
Kauj ruam 10
Sim tig rau ntawm lub suab nrov. Cov LED ntsuab yuav tsum taws. Thaum hloov mus, ceev faj kom tsis txhob xuas tes kis ntawm transistor nrog koj ob txhais tes, vim tias tag nrho qhov hluav taws xob tas li ntawm 50 volts lossis ntau dua ua haujlwm nruab nrab ntawm lawv lub cev. Qhib lub amplifier rau 30 vib nas this, tom qab ntawd tig mus rau nws thiab ntsuas qhov ntsuas kub ntawm qhov xwm txheej ntawm cov zis transistors. Yog tias qhov kub ntawm qhov teeb meem transistor tsis ntau tshaj 2 degrees siab dua qhov nws tau ua dhau los, tom qab ntawd koj tuaj yeem nyab xeeb ua ke nrog lub suab nrov.
Kauj ruam 11
Txuas txhua cov xov hluav taws xob los ntawm cov teeb meem loj, roj tawm txhua qhov heatsink ntawm qhov tso zis hluav taws xob thiab cov khoom siv hluav taws xob tuav nrog cov hluav taws xob ua kom sov, muab cov roj hmab-npuag gaskets rau lawv uas nyob hauv qab, lossis hloov nrog mica gaskets.
Kauj ruam 12
Ntsia rov qab tag nrho cov ntsia hlau nrawm uas tuav lub rooj tsavxwm, thiab tom qab ntawd nruab ib txoj hlua khawm ceev ntawm cov zis hluav taws xob thiab cov khoom siv hluav taws xob tuav. Tom qab txhua txoj hlua kab tiav, xyuas tias tsis muaj hluav taws xob sib txuas ntawm cov kis ntawm transistor thiab kis amplifier. Tom qab ntawv hloov hauv qab daim npog.
Kauj ruam 13
Nruab lub amplifier rov qab ntawm lub tshuab, nco ntsoov tias nws txuas nrog kom raug.
