The amplifierbased on theclassHfromPhilipsaudioamplifierIC,itcandeliver36WRMS and 70Wpower music,allfromthe supplyvoltage of13.8V. Thisamplifiercanprovide36WRMScontinuousinto4ohmloadwhen using a13.8Vsupply. However,itisable todeliver70Woutputpowersignal(music)inthe dynamiccondition. As we cansee fromthe drawingsand schematic diagrams,thispowerfulamplifieruses onlyfewpart. As we cansee fromthe schematicdrawingsanddiagrams,thispowerfulamplifieruses onlyfewpart. It is builton aPCBsize104mmx39mm,buteven thoughits sizemay be simple,butnot withhis ability.Thisamplifieralsohas excellentnoise anddistortion.
