The AMP6 amplifier is the circuit board that powers the motor in most TigerStop positioners, including TigerStop, TigerFence, TigerCrossCut, and others. It requires a CON5 controller and is not compatible with older models. The price includes a $200 core charge, refunded when the previous amplifier is returned within 30 days. It’s essential to test the motor before ordering to prevent damage to the new amplifier. The machine’s serial number is required for shipping.
