Engineered specifically as the high-gain \u003cstrong\u003evoltage amplification stage\u003c\/strong\u003e, this module is designed to drive high-power output sections delivering an impressive \u003cstrong\u003e120W to 150W per channel\u003c\/strong\u003e with clinical precision.\u003c\/p\u003e\n\n\u003cp\u003eThis \"Mark III\" variant is the most advanced in the 3152 family, featuring an internal current mirror circuit that achieves a staggering 0.005% Total Harmonic Distortion (THD). It is a critical component for restoring flagship-level vintage Hi-Fi receivers and massive power amplifiers where signal integrity is the highest priority.\u003c\/p\u003e\n\n\u003ch4\u003eKey Technical Features:\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Professional voltage amplification for 150W stereo power stages.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUltra-Low Distortion:\u003c\/strong\u003e Audiophile-grade 0.005% THD due to refined current mirror architecture.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e 2-Channel (Stereo) in a 15-pin hybrid package.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh Voltage Handling:\u003c\/strong\u003e Designed for high-rail dual supplies (Maximum ±90V; Recommended ±60V to ±72V).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStability:\u003c\/strong\u003e Optimized AC amplifier configuration eliminates the need for external midpoint adjustment circuits.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eInstallation \u0026amp; Safety:\u003c\/h4\u003e\n\u003cp\u003eThe STK3152III operates at very high voltages. Ensure all power supply filter capacitors are fully discharged before installation. Because this module drives the final power stage, any short in the output transistors can immediately damage a new STK3152III. We strongly recommend a full diagnostic of the output stage and emitter resistors before powering up.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003ePro Tip: Use premium thermal grease and ensure a perfectly flat mounting surface to maintain the thermal stability required for 150W-class performance.\u003c\/em\u003e\u003c\/p\u003e","brand":"Sanyo","offers":[{"title":"New","offer_id":48006074597530,"sku":"SC0007","price":34.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/9477\/8778\/files\/21-STK3152III_20Sanyo_20Voltage_20Amplifier.jpg?v=1778389428","url":"https:\/\/prellelectronics.com\/products\/stk3152iii-sanyo-audiophile-voltage-amplifier-driver-ic-150w","provider":"Prell Electronics","version":"1.0","type":"link"}
