Completely clean away all old, hardened thermal paste from your chassis heatsink plate. You must apply a fresh, thin, uniform layer of high-quality silicone thermal grease across the entire metal backing plate of the STK401-140 prior to bolting it down tightly.\u003c\/em\u003e\u003c\/p\u003e","brand":"Sanyo","offers":[{"title":"New","offer_id":48038271221914,"sku":"SC0009","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/9477\/8778\/files\/25-STK401-140_20Thick-Film_20Hybrid_20IC_20-_202-Channel_20120W_2B120W_20Audio_20Power_20Amplifier.jpg?v=1778962477","url":"https:\/\/prellelectronics.com\/products\/stk401-140-sanyo-thick-film-hybrid-ic-120w-stereo-power-amplifier","provider":"Prell Electronics","version":"1.0","type":"link"}
