Good afternoon po boss Tanong ko lng po panu po ayusin ang relay circuit nag ayaw gumana ang relay pag nka kabit ang 4148 na diod piro pag hinang ko nag switch ang relay Anu Po dapat palitan na piyesa

Sa amplifier po ba gamit yong relay. Hindi po nag suswitch-on ang relay kung may nadedetect na problema sa main amplifier.
