Usagi Electric | Restoring an HP 150A Oscilloscope (Part 3) @UsagiElectric | Uploaded September 2021 | Updated October 2024, 1 day ago.
This HP scope is taking absolutely no prisoners when it comes to repairs, but I’m nothing if not stubborn. So, in this episode, we take yet another crack at the HP scope and while we only make very little progress, we do actually make progress and that’s a win in my book!
