hmmm talagang magaarc yan kung aalisin mo sa tube

baka naman kasi madumi yung paligid nung kinakabitan ng cap? ganito po gawin nyo tanggalin nyo po power ng circuit tapos idischarge nyo tube then kuha po kayo ng basang basahan "yung hindi tumutulo ha" yung tama lang ang pagkabasa tapos punasan nyo yung paligid nung pinagkakabitan ng CAP

tapos pag napunasan nyo na gawin nyo rin po yan sa cap

tapos pag ikakabit nyo na po haguran nyo po ng konting silicon compound yung sasayaran ng cap para lumagkit lang kahit waag na magkulay tapos kabit mo po yung cap
