Ensure the heatsink is polished clean of old residue and apply a fresh, even layer of non-conductive thermal grease. Always verify the voltage of your split power supply rails before installing the new IC to prevent immediate failure.\u003c\/em\u003e\u003c\/p\u003e","brand":"Sanyo","offers":[{"title":"New","offer_id":48005785813146,"sku":"SC0006","price":31.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/9477\/8778\/files\/36-Sanyo_20STK4137MK2_202-Channel_20Stereo_20Audio_20Power_20Amplifier_20-_2020W_2B20W.jpg?v=1778362586","url":"https:\/\/prellelectronics.com\/products\/sanyo-stk4137mk2-2-channel-stereo-audio-amplifier-20w","provider":"Prell Electronics","version":"1.0","type":"link"}
