its a vu meter
*edit* yep this is definitely a vu meter,although i dont know why you didnt use smd capacitors isntead it would make it like 3 times smaller
*another edit* i was told that it wasnt a vu meter so i withdraw my previous statement,but it looks like one lol,those capcitors are very large for the psp though,if it aint a vu meter i ahve no clue what it is
