Williams Hurricane PowerDriver MPU and preDCS Sound Board Overall Checkout

Chris Hibler walks through a repaired Williams Hurricane power driver board, MPU (NVRAM installed), and preDCS sound board upgrades, following Dave Riggore's recommended sound board capacitor changes. He runs the switch matrix, direct switch, solenoid, lamp, and sound tests, and notes an upgraded voltage watchdog threshold (4.27V vs factory 4.75V) that makes the board more reset-resistant. The video is primarily a repair walkthrough rather than industry news.
