This video was featured on EEVblog in January. You can skip it if you have already watched it on Dave's channel. I am putting it here just for completeness.
In this video I did a teardown of an HP 493A microwave amplifier and took a look at what's inside the traveling wave tube. I did a detailed teardown of another HP 493A several years ago and you can find the details here: [ Ссылка ]
