I will follow the search plan provided in the hints. I'll start by performing the searches as outlined. search results for "C1124 transistor datasheet" show a mix of irrelevant results and potential leads. Result 0 is from tecsho.com, which might have a datasheet. Result 1 from en.eeworld.com.cn is about an inductor, not a transistor. Result 2 is from file.jotrin.com and mentions Oki Electric and DIP-40P, which seems like a different component. Result 5 is about 2SA1124, which might be related. Result 7 is about KTB1124, which might be a similar transistor. This link or copies made by others cannot be deleted

Enhances efficiency and reduces power dissipation during fully-saturated switching states. Excellent Linearity of hFEh sub cap F cap E end-sub

A superior datasheet includes graphs for . This helps you identify the "knee" of the transistor, ensuring you aren't operating too close to the saturation point where distortion occurs. 2. Safe Operating Area (SOA)

: This is arguably the most popular and recommended direct replacement, especially for its use in the Sony STR-7045, where the original 2SC1124 had failed, causing a resistor to burn out. The KSC2690 is well-regarded for its high gain, excellent linearity, and low noise, which are critical for preserving audio fidelity. A critical point from restorers is that the pinout of the KSC2690 is ECB (Emitter-Collector-Base) , whereas the original 2SC1124's pinout is EBC (Emitter-Base-Collector) . Therefore, you must "bend the leads to fit the old pin-out, ie swap C and B." Try again later
