Hi Jeffrey,
thanks for your answer and recollections on the famous hammer test ;-) > hangar. I was mesmerized as two weights were released from two chains > on opposite sides of the machine as it was running. The two weights There is a youtube video showing some of the testing... https://www.youtube.com/watch?v=_oOgYklBklc ..but the hammer is not hitting the device under test directly, but it is hitting a big steel plate where the device is mounted to (indeed simulating a submarine in harsh "conditions")... > up the Liberty bell, or crashed a VW into a lightpole. The machine > continued to function! Yes, lot of metal inside those Rolms. Although all Aluminium, they are veeery heavy and I always wondered how many of them also have been used in airborne applications, where weight is an issue ;-) Best wishes, Erik.
