Power up and tear down of a Rohde & Schwarz SKTU BN 4151/2/5 noise generator

This noise generator from 1958 has been sitting on a shelf for year, even decades. If I should power it up suddenly, it would probably die. In this video, I explain how to slowly power up an old device to prevent it from releasing the magic smoke. At the same time I study the design choices the engineers from the past made in order to build a device with a bandwidth of 1 GHz.
