Ob peb lub hlis dhau los Kuv tau lees paub tias kuv Yamaha THR 10C muaj teeb meem nrog cov pob qhov cuam tshuam. Nws tsis muaj peev xwm cuam tshuam Chorus cov nyhuv ntxiv hauv Knob txoj haujlwm xoom. Kev hloov pauv/ntawm lub amp ib yam rov pib dua rau lub Hoobkas teeb tsa tsis txhim kho qhov xwm txheej. Tib txoj haujlwm ua haujlwm yog txhawm rau txuas lub amp rau lub khoos phis tawj thiab ua rau Chorus effect siv THR lub khoos phis tawj "THR Editor" thiab tom qab ntawd txuag cov chaw hauv tus neeg siv nco. Ib qho kev daws teeb meem no tsis txaus siab kuv ntev.

Kuv tshawb hauv internet rau kev daws teeb meem los daws qhov teeb meem no. Hmoov tsis kuv tsis pom dab tsi ntawm qhov teeb meem tshwj xeeb no. Nov yog qhov laj thawj tseem ceeb rau kuv los sau cov lus qhia no. Kuv vam tias nws yuav pab lwm tus uas ntsib teeb meem zoo ib yam lossis zoo ib yam.

Kuv yuav daws qhov teeb meem li cas?

Kuv thawj lub tswv yim yog qhov feem ntau tej zaum qhov tsis kam ntawm lub zog ntawm lub pob qhov rooj tuaj yeem hloov pauv (nce) hauv lub neej thiab yog li YAMAHAs microcontroller/DSP tsis tuaj yeem txheeb xyuas qhov "deactivation" voltage theem ntxiv. (qib hluav taws xob ntawm micorcontroller cov tswv yim rau siab). Yog li kuv txiav txim siab pib kho los ntawm kev hloov lub hwj chim thiab saib seb qhov no tuaj yeem daws qhov teeb meem.

Thaum kawg nws tau daws qhov teeb meem thiab kuv yuav tsum hais tias kev kho nws tus kheej tsis nyuaj thiab tau ua tiav li ntawm 30 feeb vim tias lub amp tuaj yeem muab sib dhos tau yooj yim heev thiab nws tsis yog qhov teeb meem los qhib lub potentiometer PCB.

Ua ntej thaum kawg qhib lub amp Kuv tau tshawb xyuas cov lus qhia "Rov Kho Yamaha THR10 Hloov" https://www.planetz.com/repairing-yamaha-thr10-swi… lays tawm cov ncauj lus kom ntxaws yuav qhib thiab disassemble lub amp.

Cov kauj ruam ua haujlwm yog dab tsi?

1. Kuv xaj tus tshiab potentiometer (YAMAHA THR 10 khoom seem potentiometer)

   Lub vev xaib uas kuv xaj cov khoom seem:

2. Qhib thiab disassembled lub amp kom txog thaum kuv muaj peev xwm tso lub potentiometer PCB qhib
3. Desoldered qhov tsis zoo potentiometer
4. Resoldered tus potentiomenter tshiab
5. Reassembled lub amp
6. Kuaj thiab Ua tiav

Kauj Ruam 1: Tshem Tawm Cov Ntsia Hlau

Pib tshem 3 cov ntsia hlau nyob tom qab ntawm lub amp thiab ob lub ntsia hlau ntawm lub hauv ntej taw ntawm lub amp.

Kauj Ruam 2: Tshem Bolts

Tshem tawm 4 tus ntsia liaj qhov rooj rau pem hauv ntej nrog tus ciaj ntswj

Kauj Ruam 3: Cais Cov Hlau Sab Saum/Pem Hauv Ntej Ntawm Cov Yas Dub Rov Qab/sab

Cais cov hlau saum/pem hauv ntej los ntawm cov yas dub rov qab/sab thiab tom qab ntawd

Tshem tawm 3 qhov txuas txuas hlau sab saum toj/pem hauv ntej nrog cov yas dub rov qab/sab. Koj tuaj yeem tso cov yas dub thim rov qab/sab ntawm ib sab thiab txuas ntxiv nrog nres tom ntej nrog rau sab saum toj/hauv ntej.

Kauj ruam 4: Tshem cov pob qhov rooj

Tshem cov pob qhov taub los ntawm pob qhov rooj thiab tshem cov txiv ntoo thiab cov ntxhua khaub ncaws. Koj tsis tas yuav tshem lub pob qhov rooj thiab cov txiv ntseej los ntawm AMP tus tuav lub pob qhov rooj (raws li pom hauv daim duab) vim tias nws nyob ntawm PCB sib txawv uas tuaj yeem nyob sab hauv.

Kauj Ruam 5: Tshem Tawm Cov PCB tseem ceeb

Tshem tawm ob lub hau ntswj ntawm lub PCB tseem ceeb thiab txuas ob lub txuas.

Kauj Ruam 6: Tshem Tawm Potentiometer PCB

Tshem tawm ib lub hau ntswj tuav lub hwj chim PCB thiab tom qab ntawd tshem tawm PCB. Tam sim no nrhiav thiab khij lub potentiometer tawg. Kuv siv tus cim yooj yim rau nws.

Kauj Ruam 7: Desolder Broken Potentiometer

Pib nrog qhov ua kom lub zog qis dua siv cov hlau txuas thiab lub tshuab nqus dej (lub tshuab nqus dej desoldering). Tshem tawm cov potentiometer tawg thiab hloov nws nrog cov khoom seem.

Kauj Ruam 8: Solder Tshiab Potentiometer

Ntxig lub potentiometer tshiab (seem seem) thiab muab tshuaj txhuam rau nws. Txheeb xyuas cov khoom sib txuas thiab ua tau luv luv Circuit Court.

Kauj Ruam 9: Rov ua dua

Tam sim no, kev ua haujlwm tiav thiab koj tuaj yeem pib rov sib sau ua ke txhua qhov (PCBs, txuas txuas) hauv qhov kev thim rov qab zoo li peb tau tshem tawm txhua qhov.

Tom qab rov tsim dua tau ua tiav lub hwj chim thiab sim nws. Yog tias txhua yam tau ua tiav kom raug amp yuav tsum rov ua haujlwm dua thiab teeb meem yuav tsum daws. Hauv kuv qhov teeb meem tau daws lawm.
