The PF-500 circuit is divided into two primary sections: the and the Main Power Board .
"Dead," he cursed. He looked back at the schematic. The drawing showed a path from the IEC inlet, through the fuse, into the switching transistors. He traced it with his finger, stopping at a cluster of resistors near the MOSFETs. R401. The schematic called it a "current-sensing resistor." ampeg pf500 schematic
"Gig's on," Elias said, grabbing his toolbox. The PF-500 circuit is divided into two primary
