Designed for split-rail power supplies, this module provides a consistent 6W + 6W stereo output. It is the primary replacement part for restoring high-quality audio in compact vintage stereos, active desktop monitors, and premium radio equipment from the 1980s and 90s.\u003c\/p\u003e\n\n\u003cp\u003eAs the foundation of the STK4102II series, it features a built-in muting circuit to suppress \"pop\" noise and an internal architecture designed for low harmonic distortion (0.4% THD), delivering the signature warm sound Sanyo modules are known for.\u003c\/p\u003e\n\n\u003ch4\u003eKey Technical Features:\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContinuous Power Output:\u003c\/strong\u003e 6W + 6W (at 8Ω, THD = 0.4%)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e 2-Channel Stereo (18-Pin SIP Package).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Compatibility:\u003c\/strong\u003e Pin-compatible with the entire series up to 50W (STK4102II to STK4192II).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e Full-range capability from 20Hz to 50kHz.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e Recommended ±13.2V (Absolute Maximum ±20.5V).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThermal Advantage:\u003c\/strong\u003e Guaranteed operation up to 125°C substrate temperature.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eInstallation \u0026amp; Thermal Management:\u003c\/h4\u003e\n\u003cp\u003eThe STK4102II \u003cstrong\u003erequires\u003c\/strong\u003e a heatsink and thermal grease for safe operation. Because the internal power transistors are bonded directly to the substrate, even a brief test without a heatsink can cause immediate and permanent damage.
