i think may mali sa ginawa nyo, (wag excited) bago isaksak check nyo mabuti kung tama ung wirings, solders sa PCB (trace nyo mabuti ung PCB) at connections ng psu

check nyo din datasheet ng IC

pakipost po ung schematic at tsaka ung ginawa nyo na din (picture)

ano pangalan ng IC sis?

power supply specs?

subs

TDA 2030 po ang IC, power supply is ==16V at -16V, di kaya posible po kayang baliktad ang tapo ko ng power yung negative na tap sa + at yung positive na tap- na paa ng IC?
