: While similar to other STK411 models (like the 240E or 230E), always verify voltage requirements. For example, if a circuit specifies a 240V part, you should not downgrade to the 210V version. Reference Resources
Typically remains below 0.1% to preserve audio signal integrity. Pinout and Internal Architecture
The represents a golden era of modular hi-fi amplification. While no longer in production, its datasheet reveals a robust, low-distortion, and easy-to-use amplifier IC that still serves vintage audio restoration well. Understanding its pinout, thermal requirements, and application circuit is essential for anyone looking to repair legacy equipment or build a retro-style stereo amplifier.
The “E” suffix likely indicates:
Delivers approximately 105W x 2 channels into an 8Ω load.
Features thick-film technology, ensuring durability in audio applications. Applications
