Turn the Vario-Strength knob to restore the punch to your flippers: ramps become accessible again, the ball goes exactly where you aim, and the entire machine feels brand new. Speed ​​is addressed on two levels. From the moment it’s installed, Fortress regulates power to the coils, ensuring full-strength activation every single time you press the button. Then, "Hit-to-Flip" takes it a step further: the board reads the button input and controls the coil directly—while still adhering to all CPU-defined power and hold instructions—reducing the signal round-trip time to a mere fraction of what it was. Fortress continuously monitors the +5V and +12V logic supplies, the flipper power rail, and the current flowing through each MOSFET. Everything is displayed via "Smart Status" LEDs. Proactive MOSFET protection across all 8 control channels. Real-time rail voltage monitoring with validation and alert thresholds. Compatible with Bally / Williams / WPC systems. Designed as the ultimate flipper system upgrade, the Fortress Fliptronic replaces both Fliptronic I and Fliptronic II boards with a single, unified unit. It features adjustable "Vario-Strength" flipper power, the ultra-responsive "Hit-to-Flip" technology, and comprehensive self-diagnostics—all engineered to restore the snappy, factory-fresh feel to your Bally/Williams WPC pinball machine. A direct, drop-in replacement: no soldering, no permanent modifications, and completely reversible! Reconnect with your flippers and play your classic machine as if it had just rolled off the assembly line! Fortress Fliptronic breathes new life into your gaming experience.
