This video covers the basics of using a scope on Tube Audio gear. I cover the various types of scopes, how the controls and probes work, some safety concerns, and how to use a signal generator to do a quick test of a tube amp's power output.
Here are two very good videos going into further detail on ground isolation of the device under test and how not to blow stuff up. NEVER try to isolate or float the scope, always float the device you are testing!

I plan to go into more detail on using a scope in the Nobsound 6P1 series, but I wanted to do a stand alone basics video for beginners before we get started.
Again, tube audio gear has lethal voltages inside them, even after they have been powered off. DO NOT OPEN THEM UP unless you 100% understand all the safety protocols needed to work on them safely!!
