He soldered it in. Sweat dripped from his nose onto the paper schematic, smearing the ink of the input stage.
"Power supply," he whispered, tracing the thick red lines on the paper. The PF500 was known for its switching power supply—a high-efficiency beast that kept the amp light but required precise voltages. He probed the main transformer pins.

Elias wiped grease from his forehead with the back of a hand that was trembling, just slightly. On the workbench before him sat the patient: an Ampeg PF500 Portaflex head. It was sleek, black, and utterly silent. To the untrained eye, it was a modern, lightweight bass amplifier. To Elias, currently staring into its open chassis, it was a labyrinth of failure.
