Typically 100W to 120W per channel (depending on the specific circuit implementation and load).
If replacing the module, ensure you apply a fresh, thin layer of high-quality silicone thermal grease between the IC and the heat sink. Overheating is the #1 cause of failure for these hybrids.
The is a thick-film hybrid integrated circuit (IC) designed by Sanyo (now part of ON Semiconductor) for high-fidelity audio power amplification. Part of the renowned STK series, this module is specifically engineered for Class H audio amplification, providing high efficiency and robust power output for home stereo systems and AV receivers.
