Positive Grid Spark Mini Amp
Repairing a Positive Grid Spark Mini Amp with a broken USB-C charging port and trace damage on the PCB required a careful and highly precise approach to restore the unit to full working order. The customer reported that the amp would no longer charge, and upon inspection, it became evident that the USB-C port had become detached from the PCB and which had also caused lifting and breaking of delicate PCB traces from the USB-C connector. To resolve the issue, the amp was carefully disassembled to expose the charging circuitry, and the damaged PCB traces, which were meticulously repaired using micro-soldering techniques and fine jumper wires to restore full continuity across the broken connections. A brand-new, high-quality USB-C port was then fitted and securely soldered into place, ensuring a strong and reliable connection capable of withstanding regular use. After reassembly, the amp underwent extensive testing to verify that it was charging correctly, holding power as expected, and performing without any issues. The customer was extremely pleased with the outcome, as the Spark Mini Amp was restored to perfect working condition, allowing them to continue using it both as a practice tool and portable speaker. The quoted price of £95, covering the cost of labour, precision repair of the PCB, and the new USB-C port, was considered very fair given the complexity of the repair. This successful job not only brought the amp back to life but also highlighted the importance of skilled workmanship when repairing delicate modern audio equipment.
