TRW Inc. is a well known producer of high quality electronic components. I have found their products to have a very long life and their specs are near the top of the list. They aren’t as well known in the audio world, but I can easily recommend them. TRW also built the Pioneer 1 and Pioneer 10 spacecraft!
