    Thank you very much for the info. This is an IC for a Marantz amplifier and it was easy to find a replacement about 3 years ago. It was damaged due to high temperature in our place. We forgot to turn on the room fan. It is extremely hard to obtain this thing nowadays. Again, thanks for your attention.

    Marantz was a very high quality American brand.
    The amplifier circuit is made by Sanyo which is a low quality Japanese brand.

    Now Marantz is owned by a Japanese holdings company who own many other previously-American brands. Good-bye to quality.

    Now, I understand why it is difficult to obtain the part. I bought this model in the 1990´s from Hongkong. It was made in Japan. Thanks for your advise.

    First of all, I wish to thank everyone for their response to my question. Second, I wish to apologize because I made a mistake in identifying the component´s part number since it was almost erased and can not be identified properly. The correct part number was STK 4164 MK II which can be easily found at alldatasheet.com from the reply posted by rogs. I wish I could return the favor in the future. Thanks again and sorry for the error.
