this Brüel & Kjær 1024 Sine Random Generator
has been driving me nuts for a few days,
arc over near output amplifier and attenuator switches

I made a little video to entertain you with all my findings

It would be interesting to know what happened. I was not able to listen to the video.
This is one of the most useful Brüel & Kjaer instruments.
