Thoroughly scrape away all old, hardened thermal compound from your amplifier's aluminum heatsink block. Apply a fresh, thin, and uniform layer of silicone thermal grease across the entire metal backing plate of the STK402-050 before tightening down the mounting screws.\u003c\/em\u003e\u003c\/p\u003e","brand":"Sanyo","offers":[{"title":"New","offer_id":48038271647898,"sku":"SC0009","price":14.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/9477\/8778\/files\/33-STK402-050_20Thick-Film_20Hybrid_20IC_20-_202-Channel_20Class-AB_20Audio_20Power_20Amplifier.jpg?v=1778962498","url":"https:\/\/prellelectronics.com\/products\/stk402-050-sanyo-thick-film-hybrid-ic-audio-power-amplifier","provider":"Prell Electronics","version":"1.0","type":"link"}
