    • Here is the Harman/Kardon HK3700.

    • Please be careful with the high voltage capacitors and other components inside. I am not responsible for any of your actions as a result of this guide.

    • Using a P2 phillips screwdriver, you can remove all screws on the sides and back of the unit. After those are removed, you can remove the top cover by sliding it towards the back and then lifting away.

    • Your top cover will probably not be dented in like mine is.

    • I did not remove the transistors from the heat sink, but you can with a phillips screwdriver and something to separate the transistors from their thermal compound.
