This IC is a Class-AB amplifier, which is less efficient than modern Class-D designs. It will generate significant heat, especially at high volumes. If it gets too hot, check the following: If you want to move forward with your

): Critical for determining the size of the required heatsink. Usually rated up to 150°C. Storage Temperature: -30°C to +125°C. 3. Electrical Characteristics Under standard operating conditions (typically ), the STK411-210E delivers: It will generate significant heat, especially at high

Replacement parts for vintage audio equipment (Sanyo, Sony, and AIWA frequently used these modules). If you are looking to repair a device build a new amplifier , would you like: circuit diagram (schematic) for a typical application? compatible replacement/equivalent Troubleshooting steps for a blown STK module?

This is the most common cause of failure. Ensure the thermal paste between the IC and the heatsink is fresh and that the heatsink is free of dust.

voltage on your speaker output terminals, the internal output transistors have shorted out. You must replace the hybrid IC. Thermal Management and Replacement Workflows
