HP 461A Amplifier 1kHz to 150MHz repair test teardown

[@arenaengineering8070]

Interesting amplifier. Look's like a distribution tv wire amplifier .Thanks for the video.👍🏻

it is mainly made for lab experiments, TV distribution amps look a bit similar that is right, but the frequency range is 40 to 800 MHz and gain dont need to be perfectly flat stable or accurate, so it can be made much cheaper.

Hi Thomas, nice video, I would like to ask you if you can make a video on the HP8508A vector voltmeter, because there is little information on the internet, and I would like to better understand the measurements that can be made with this instrument. a warm greeting from Italy
