Technician’s Note: Precision audio modules like the STK4137MK2 require excellent thermal contact. Ensure the heatsink is polished clean of old residue and apply a fresh, even layer of non-conductive thermal grease. Always verify the voltage of your split power supply rails before installing the new IC to prevent immediate failure.
