5Pcs Original 2SJ103 2SK246 Matched FET Pairs J103 K246 TO-92 Field-Effect Transistors for Hi-Fi Audio
Product Description:
The 2SJ103 (P-channel) and 2SK246 (N-channel) are ultra-low-noise, matched JFET pairs designed for high-fidelity audio amplification and precision signal processing. Housed in compact TO-92 packages, these transistors are ideal for audiophile-grade preamplifiers, microphone circuits, and vintage synth repairs, offering exceptional input impedance (>100MΩ) and low distortion for crystal-clear sound reproduction.
Applications:
Hi-Fi Audio: Phono preamps, headphone amplifiers, and tube amplifier input stages.
Professional Audio: Condenser microphone capsules, mixing consoles, and studio compressors.
Vintage Electronics: Restoring classic synthesizers (e.g., Roland TB-303, Yamaha DX7).
Instrumentation: Low-noise sensor interfaces and medical-grade signal conditioning.
DIY Projects: Guitar pedal mods, RIAA equalizers, and analog synthesizer builds.
