Hello, long time no see!
I picked up one of these subs but it seems to not want to power up? I have checked the fuse at the switch and it is good. The switch itself is functioning and i made it to the rectifier and it is testing good too... I believe just before the fwbr is a regulator transistor, it also tests good. This unit is a switching psu i think, so i need a bit of help as i am not super familiar with these newer designs. Not having a schematic is not helping at all either! Fwiw this amp module is supposed to be similar to a Velodyne DLS-3750r. Thanks in advance!
