Delivering a reliable \u003cstrong\u003e5 Watts per channel\u003c\/strong\u003e, this 15-pin module was a standard component in high-quality portable stereo systems (Boomboxes), tabletop radios, and compact televisions throughout the 1980s. It is highly sought after by restorers for its efficient design and clear analog sound.\u003c\/p\u003e\n\n\u003cp\u003eUtilizing Sanyo’s Insulated Metal Substrate Technology (IMST), the STK4332 offers stable performance in a small, slim package. With a Total Harmonic Distortion (THD) of 1.0% at full power, it is the definitive replacement part for bringing small-scale vintage audio equipment back to its original factory performance.\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 5W + 5W (at 8Ω, f = 1kHz, THD = 1.0%).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e 2-Channel Stereo in a standard 15-Pin SIP (Single In-line Package).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLow-Profile Design:\u003c\/strong\u003e Slim package height of 25.5mm for space-constrained enclosures.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e Full-range high-fidelity from 50Hz to 50kHz (+0, -3dB).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThermal Durability:\u003c\/strong\u003e Guaranteed operation up to 125°C substrate temperature.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecommended Supply Voltage:\u003c\/strong\u003e 23V DC (Maximum 32V).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eInstallation \u0026amp; Safety Guide:\u003c\/h4\u003e\n\u003cp\u003eAlthough the STK4332 is a low-power module, it still requires proper thermal management.

We strongly suggest checking the output coupling capacitors, as dried-out electrolytic caps in vintage boomboxes are a primary cause of module stress and audio distortion.\u003c\/em\u003e\u003c\/p\u003e","brand":"Sanyo","offers":[{"title":"New","offer_id":48013257015450,"sku":"SC0008","price":15.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/9477\/8778\/files\/20-STK4332_20Sanyo_20AF_20Power_20Amplifier.jpg?v=1778557064","url":"https:\/\/prellelectronics.com\/products\/stk4332-sanyo-2-channel-af-power-amplifier-5w-5w","provider":"Prell Electronics","version":"1.0","type":"link"}
