    Good job then!

    Get yourself a tube of thermal paste, and have at it. Replace with OEM equivalent, or better.

    Don't forget the mica insulator when you reassemble it!

    I will have to say the part your you have a pic of is either the audio chip or the volatage regulator. It is possible for this part to get warm and be operating ok, but if it gets so warm that you cant touch it then that is another thing. Do you have any cold spray around or at least a can of air; then you can try spraying some on the heated parts and see if that brings more life into the radio and if it does you can try to locate a replacement part, but in some cases it may be something behind this part that caused it to fail. Your senses are your best tool, take a magnifying glass and go around and look for and charred or burnt parts and you sense of feel if anything else seems to be getting quite warm especially in the are on the back of the radio where there should be one or two transistors with 3 pins mounted to the chasis and are the driver transistor and final transistor stages of the RF. Take a look around and write down anything unusual or take pics and note any heated parts while RX and TX. Good luck.
