Stk413-430 Circuit Diagram _hot_

If no direct replacement is available and the original part is obsolete, the only viable route may be to design a new amplifier circuit using modern discrete components, though this is a significantly more involved process.

Due to its reliability and high fidelity, this IC is widely used in: : Stereo and home theater amplifiers. stk413-430 circuit diagram

Boosts the voltage level of the input signal to drive the output stages. If no direct replacement is available and the

rated at 63V or higher per rail) are required to eliminate hum and provide instant current during bass heavy audio peaks. rated at 63V or higher per rail) are

Pins 6 and 11 (NF – Ripple Filter) are often connected to ground via a 100µF capacitor to reduce power supply hum. A small resistor (220Ω) from these pins to ground may also be included.

The circuit requires a robust transformer with a center-tapped secondary coil (e.g., 35V-0V-35V AC).
