Qhov ntsuas hluav taws xob ntawm lub kaus mom koj siv hs tsis muaj kev cuam tshuam rau lub suab tab sis yuav tsum muaj qhov tsawg kawg ntawm 16V.

Kauj Ruam 5: Tus Nqi Tsawg Passer

So yog tias koj siv kuv qhov txiaj ntsig koj tsuas yog yuav tsum pauv C13 ntawm 22nF rau 220nF thiab C14 los ntawm 10nF txog 100nF.

Kauj Ruam 6: Hloov Kho Zaus Cov Lus Teb ntawm Cov Hluav Taws Xob

qhov no yog ua tiav yooj yim heev, koj tsuas yog yuav tsum tau desolder thiab rho tawm C9 kom tau qis dua qhov ua tau zoo dua qub.

Kauj ruam 7: Koj tau ua tiav

tam sim no muab lub rooj tsavxwm tso rau hauv rooj plaub, ntswj tag nrho ua ke dua. uas yog nws. Txhawm rau siv nws txuas lub woofer (4Ohm muab lub zog feem ntau) ntawm lub tswb (RCA phono) ntsaws. Nco ntsoov tias tus neeg hais lus tuaj yeem tiv taus yam tsawg kawg ntawm 20Watts. muaj kev lom zem.
